描述 Description

The NMUX1308-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 NMUX1308-Q100 is dual source compatible with existing 4851 and 4051 devices. The NMUX1308-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 a common input/output (Z) and eight independent inputs?/?outputs (Y0 to Y7). 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 four control signal pins (S0, S1, S2, and E). S0, S1, and S2 determine the analog channels to connect between Z and Yn. E can 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.
