7. Precautions during use
(1) Maximum rating The maximum ratings are the limit values which must not be exceeded during operation of device. None of these rating value must not be exceeded. If the maximum rating value is exceeded, the characteristics of devices may never be restored properly. In extreme cases, the device may be permanently damages. Soldering Optical modules are comprised of internal semiconductor devices. However, in principle, optical modules are optical components. During soldering, ensure that flux does not contact with the emitting surface or the detecting surface. Also ensure that proper flux removal is conducted after soldering. Some optical modules come with a protective cap. The protective cap is used to avoid malfunction when the optical module is not in use. Note that it is not dust or waterproof. As mentioned before, optical modules are optical components. Thus, in principle, soldering where there may be flux residue and flux removal after soldering is not recommended. Toshiba recommend that soldering be performed without the optical module mounted on the board. Then, after the board has been cleaned, the optical module should be soldered on to the board manually. If the optical module cannot be soldered manually, use non-halogen (chlorine-free) flux and make sure, without cleaning, there is no residue such as chlorine. This is one of the ways to eliminate the effects of flux. In such a cases, be sure to check the devices'reliability. Noise resistance It is believed that the use of optical transfer devices improve noise resistance. In theory, optical fiber is not affected by noise at all. However, receiving modules which handle signals whose level is extremely small, are susceptible to noise. TOSLINK improve noise resistance to use a conductive case. However, the current signal output by the optical receiving modules' photodiode is extremely small. Thus, in some environments, shielding the case may not achieve sufficient noise resistance. First systems which incorporate TOSLINK, Toshiba recommend testing using the actual device to check its noise resistance. Use a simple noise filter on TOSLINK fiber optic transceiving module's power line. If the ripple in the power supply used is significant, reinforce the filter. The optical module is to be used in an area which is susceptible to radiated noise, increase the shielding by covering the optical module and the power line filter with a metallic cover. Vibration and shock This module is plastic sealed and has its wire fixed by resin. This structure is relatively resistant to vibration and shock. In actual equipment, there are sometime cases in which vibration, shock, or stress is applied to soldered parts or connected parts, resulting in lines cut. A care must be taken in the design of equipment which will be subject to high levels of vibration. Fixing fiber optical receiving module Solder the fixed pin (pins 5 and 6) of fiber optic receiving module TORX111 to the printed circuit board to fix the module to the board. Solvent When using solvent for flux removal, do not use a high acid or high alkali solvent. Be careful not to pour solvent in to the optical connector ports. If solvent is inadvertently poured in to them, clean it off using cotton tips. Dirt Note that dirt should not be in to a module. Optical fiber Use TOFC100 or similar product for optical fiber. When cutting optical fiber, use an edged tool such as a cutter knife. Removing the optical fiber from the module When removing the optical fiber from the module, push the ring. Note that not to pull the optical fiber out from the module without pushing the ring. The tip of the optical fiber may be cut off and remain in the module.

(10) Shielding and wiring pattern of fiber optic receiving modules To shield, connect the fixed pins (pins 5 and 6) of fiber optic transceiving module TORX111 to the GND. Where the fiber optic receiving module uses metal material, be careful that the case does not touch wiring (including land). To improve noise resistance, shield the optical module and the power line filter using a metallic cover. (11) Supply voltage Use the supply voltage within the recommended operating condition (VCC = 5 0.25 V). Make sure that supply voltage does not exceed the maximum rating value of 7 V, even for an instant. (12) Output If the receiver output is at low and is connected to the power supply, or if the output is high and is connected to GND, the internal IC may be destroyed. (13) Analogue Output Pin No.2, fiber optic receiving module TORX111, is analog output terminal for observing the received optical power as a result of measuring analog output voltage. When LED or other devices connect to analog output, use the buffer circuit. When analog output terminal is not used, do not connect any circuit to it. (14) Soldering condition Solder at 260C or less for no more than three seconds. (15) Precautions when disposing of devices and packing materials. When disposing devices and packing materials, follow the procedures stipulated by local regulations in order to protect the environment against contamination. When devices are disposed of, worker safety and protection of the environment must be taken into account. (16) Precautions during use Toshiba is continually working to improve the quality and the reliability of their products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and their vulnerability to physical stress. It is the responsibility of the buyer, when utilizing Toshiba products, to observe standards of safety, and to avoid situations in which the malfunction or failure of a Toshiba product could cause loss of human life, bodily injury or damage to property. When developing equipment, please ensure that Toshiba products are used within the specified operating ranges set forth in the most recent product specifications. Also, please keep in mind the precautions and conditions set forth in the Toshiba Semiconductor Reliability Handbook.
