NMUX1308BQ-Q100X

NMUX1308BQ-Q100X is a 8-channel analogue switch multiplexer and demultiplexer with injection-current control. It is a general purpose, CMOS, bi-directional, 8 channel analogue switch, with an operating voltage range of 1.5V to 5.5V. 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 1.8V systems without the need for voltage translation. The analogue signal pins are comprised of a common input/output (Z) and eight independent inputs/outputs (Y0 to Y7). All analogue signal pins are bi-directional and support a voltage range from GND to VCC. All analogue signal pins integrate injection current control circuitry. This control circuitry isolates overvoltage spikes on disconnected analogue signal pins from coupling to the connected analogue signal path, thereby preserving measurement accuracy. Application includes body control module, battery management system, automotive head unit.
