_______________General Description
Maxim's MAX312/MAX313/MAX314 analog switches feature low on-resistance (10 max) and 1.5 on-resistance matching between channels. These switches conduct equally well in either direction. They offer low leakage over temperature (2.5nA at +85C). Low power consumption and ESD tolerance greater than 2000V per Method 3015.7 are guaranteed. The MAX312/MAX313/MAX314 are quad, singlepole/single-throw (SPST) analog switches. The MAX312 is normally closed (NC), and the MAX313 is normally open (NO). The MAX314 has two NC switches and two NO switches. All three devices operate from a single supply of +4.5V to +30V or from dual supplies of 4.5V to 20V.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current rating.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: RON = RON max - RON min. Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal range. Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25C. Note 7: Off isolation = 20log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch. Note 8: Between any two switches. Note 9: Leakage testing at single supply is guaranteed by testing with dual supplies.

__________Applications Information
Low-Distortion Audio
The MAX312/MAX313/MAX314, having very low R ON and very low RON variation with signal amplitude, are well suited for low-distortion audio applications. The Typical Operating Characteristics show Total Harmonic Distortion (THD) vs. Frequency graphs for several signal amplitudes and impedances. Higher source and load impedances improve THD, but reduce off isolation. tors to a circuit board deemed "average"; that is, designed with isolation in mind, but not using strip-line or other special RF circuit techniques. For critical applications above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz.
MAX312/MAX313/MAX314
V+
Off Isolation at High Frequencies
In 50 systems, the high-frequency on-response of these parts extends from DC to above 100MHz with a typical loss of -2dB. When the switch is turned off, however, it behaves like a capacitor, and off isolation decreases with increasing frequency. (Above 300MHz, the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances. Above 5MHz, circuit board layout becomes critical, and it becomes difficult to characterize the response of the switch independent of the circuit. The graphs shown in the Typical Operating Characteristics were taken using a 50 source and load connected with BNC connecV+
