NMUX1309PWJ

Overview

The NMUX1309PWJ is a general-purpose, CMOS, bi-directional dual 4-channel analog switch manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.5 V to 5.5 V and features two common inputs/outputs (nZ) and eight independent inputs/outputs (nY0 to nY3). The device integrates injection current control circuitry to isolate overvoltage spikes on disconnected pins, preserving measurement accuracy without external clamping components. Digital control pins support 1.8 V logic thresholds across the full operating voltage range and are 5.5 V tolerant. The component is housed in a TSSOP16 plastic thin shrink small outline package with a body width of 4.4 mm.

Feature Summary

• Integrates injection current control circuitry to divert positive and negative injection currents through a bypass FET connected to ground, minimizing supply voltage shifts and maintaining ON resistance stability.
• Features Ioff protection circuitry on both digital and analog pins that isolates internal circuits when the supply is unpowered, preventing back-powering of the supply rail and ensuring high-impedance states.
• Supports 1.8 V compatible digital logic thresholds across the entire 1.5 V to 5.5 V operating range, eliminating the need for voltage translation devices when interfacing with low-voltage GPIOs.

Applications

• Analog or digital multiplexing and demultiplexing
• System monitoring and diagnostics
• Enterprise computing
• Appliances

Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm its exact definition regarding tape-and-reel specifications or quality certifications. Ensure the TSSOP16 package variant matches the required PCB footprint dimensions. Confirm compliance with relevant environmental directives such as RoHS standards before finalizing procurement orders.

Selection Notes

Select this component for designs requiring dual 4:1 switching with rail-to-rail analog signal handling. It is suitable for systems mixing 5 V and 3.3 V applications where reducing bus width and lowering power consumption are priorities. The integrated injection current control makes it ideal for environments prone to transient spikes on long signal traces.

Part Context

The NMUX1309 belongs to the NMUX130x family of CMOS analog switches from Nexperia. This series includes the NMUX1308, which provides an 8-channel configuration. Both variants share similar electrical characteristics, including wide operating voltage ranges and compatibility with industry-standard pinouts like the 4052 and 4852 devices, facilitating direct upgrades in existing designs.

Replacement Considerations

Nexperia NMUX1309PW-Q100J is listed as a similar automotive-grade alternative.
