NMUX1309A
description
The NMUX1309A is a general purpose, CMOS, bi-directional, dual 4 channel analog switch, with an operating voltage range of 1.5 V to 5.5 V. The NMUX1309A is dual source patible with existing 4852 and 4052 devices. The NUMX1309A extends the digital logic thresholds to be patible with 1.8 V systems without the need for voltage translation.
The analog signal pins are bi-directional and are prised of a single mon input/output (Z) and eight independent inputs/outputs (Y0 to Y7).
All analog signal pins support overvoltage and undervoltage protection through the integration of injection current control circuitry. This circuit clamps analog signals biased above VCC or biased below GND, saving the need for external overvoltage and undervoltage clamp ponents (e.g. resistor diode network). This circuit also preserves measurement accuracy of the connected analog signal path by isolating overvoltage events from shifting the device operating voltage.
There are three control signal pins...
