The NMUX1308A-Q100 is a general purpose, CMOS, bi-directional, 8 channel analog switch, with an operating voltage range of 1.5 V to 5.5 V. The NMUX1308A-Q100 is dual source compatible with existing 4851 and 4051 devices. The NMUX1308A-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 bi-directional and are comprised of a single common 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 components (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 four control signal pins (S0, S1, S2, and E). S0, S1, and S2 determine the analog channels to connect between Z and Yn. Ecan be used to override S0, S1, and S2, 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.
