1. General description

The NMUX1309-Q100 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 NMUX1309-Q100 is dual source compatible

with existing 4852 and 4052 devices. The NUMX1309-Q100 extends the digital logic thresholds to

be compatible with 1.8 V systems without the need for voltage translation.

The analog signal pins are comprised of two common inputs/outputs (nZ) and eight independent

inputs/outputs (nY0 to nY3). All analog signal pins are bi-directional and support a voltage range

from GND to VCC.

All analog signal pins integrate injection current control circuitry. This control circuitry isolates

overvoltage spikes on disconnected analog signal pins from coupling to the connected analog

signal path, thereby preserving measurement accuracy. Additionally, this integration makes the use

of external overvoltage clamp components (e.g. resistive diode network) unnecessary.

There are three control signal pins (S0, S1, and E). S0 and S1 determine the analog channels

to connect between nZ and nYn. E can be used to override S0 and S1, disconnecting all analog

channels. The control signal pins support 1.8 V logic thresholds across all operating voltages.

In addition, these pins are 5.5 V tolerant, enabling up to 5.5 V operation independent of supply

voltage.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
