m pd75104, 75106, 75108 13 3.5 notes on using the p00/int4, and reset pins in addition to the functions described in sections 3.1 and 3.2, an exclusive function for setting the test mode, in which the internal fuctions of the m pd75108 are tested (solely used for ic tests), is provided to the p00/int4 and reset pins. if a voltage exceeding v dd is applied to either of these pins, the m pd75108 is put into test mode. therefore, even when the m pd75108 is in normal operation, if noise exceeding the v dd is input into any of these pins, the m pd75108 will enter the test mode, and this will cause problems for normal operation. as an example, if the wiring to the p00/int4 pin or the reset pin is long, stray noise may be picked up and the above montioned problem may occur. therefore, all wiring to these pins must be made short enough to not pick up stray noise. if noise cannot be avoided, suppress the noise using a capacitor or diode as shown in the figure below. connect a capacitor across p00/int4 and reset , and v dd . connect a diode across p00/int4 and reset , and v dd . v dd v dd p00/int4, reset v dd v dd p00/int4, reset

m pd75104, 75106, 75108 69 1 static electricity (all mos devices) exercise care so that mos devices are not adversely influenced by static electricity while being handled. the insulation of the gates of the mos device may be destroyed by a strong static charge. therefore, when transporting or storing the mos device, use a conductive tray, magazine case, or conductive buffer materials, or the metal case nec uses for packaging and shipment, and use grounding when assembling the mos device system. do not leave the mos device on a plastic plate and do not touch the pins of the device. handle boards on which mos devices are mounted similarly . 2 processing of unused pins (cmos devices only) fix the input level of cmos devices. unlike bipolar or nmos devices, if a cmos device is operated with nothing connected to its input pin, intermediate level input may be generated due to noise, and an inrush current may flow through the device, causing the device to malfunction. therefore, fix the input level of the device by using a pull-down or pull-up resistor. if there is a possibility that an unused pin serves as an output pin (whose timing is not specified), each pin should be connected to v dd or gnd through a resistor. refer to processing of unused pins in the documents of each devices. 3 status before initialization (all mos devices) the initial status of mos devices is undefined upon power application. since the characteristics of an mos device are determined by the quantity of injection at the molecular level, the initial status of the device is not controlled during the production process. the output status of pins, i/o setting, and register contents upon power application are not guaranteed. however, the items defined for reset operation and mode setting are subject to guarantee after the respective operations have been executed. when using a device with a reset function, be sure to reset the device after power application. general notes on cmos devices
