1.5 V to 5.5 V, dual 4-channel switch analog multiplexer and demultiplexer with injection-current control

The NMUX1309 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 is dual source compatible with existing 4852 and 4052 devices. The NUMX1309 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.

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
