NMUX1309BQX

NMUX1309BQX is a dual 4-channel switch analogue multiplexer and demultiplexer with injection-current control. It is a general purpose, CMOS, bi-directional, dual 4 channel analogue switch, with operating voltage of 1.5 to 5.5V. It is dual source compatible with existing 4852 and 4052 devices. It 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 two common inputs/outputs and eight independent inputs/outputs. 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. Applications include analogue or digital multiplexing/demultiplexing, system monitoring and diagnostics, enterprise computing, appliances.

• Supply voltage range from 1.50 to 5.5V, 2x SP4T-Z functionality
• Rail-to-rail operation on analogue signal pin, injection current control
• Digital pins compatible with 1.8V logic thresholds across full VCC range
• Removes need for up-translation device for compatibility with low voltage GPIOs
• Enables wider latitude for power sequencing considerations
• Isolates backflow between supply rail and any biased digital/analogue input when VCC = 0V
• Prevents any biased digital/analogue input from back powering VCC when VCC = 0V
• Maintains Hi-Z state of analogue switch when VCC = 0V
• 16 lead DHVQFN package, ambient temperature range from -40°C to +125°C
