PSMUX154ZMEX

Overview

The PSMUX154ZMEX is a high-bandwidth dual fast single-pole double throw (SPDT) CMOS switch manufactured by Diodes Incorporated. It operates within a wide supply voltage range of 1.8V to 4.3V and features an on-resistance of 4.3Ω at VDD = 3.0V, with a maximum of 6.5Ω across the industrial temperature range. The device provides rail-to-rail signal handling, an 850MHz -3dB bandwidth, and near-zero propagation delay of 250ps. It includes break-before-make switching to prevent simultaneous switch enablement, ensuring signal integrity during transitions.

Feature Summary

CMOS technology optimized for bus and analog applications
Break-before-make switching prevents signal disruption
Rail-to-rail signal range support
High off-isolation and crosstalk rejection

Applications

Portable instrumentation
Computer peripherals
Server systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS 3 compliance and lead-free status as specified in the datasheet. Ensure storage conditions remain within the recommended ambient temperature limits to maintain reliability. Validate package markings against official documentation to confirm correct date codes and manufacturing origin.

Selection Notes

Select this component when designing circuits requiring low-delay bus switching or analog signal routing. Ensure the control logic supports 1.8V, 2.5V, or 3.3V levels. Verify that the operating voltage stays within the 1.8V to 4.3V range. Consider the 10-UQFN package dimensions for PCB layout constraints.

Part Context

The PSMUX154ZMEX belongs to the PSMUX154 family of high-speed analog switches from Diodes Incorporated. It utilizes CMOS technology to achieve low on-resistance and high bandwidth. The ZM suffix indicates the 10-pin UQFN package configuration. This series is designed for applications demanding minimal signal distortion and fast switching speeds.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for potential alternatives if specific pinouts or electrical characteristics differ.

FAQ

What is the maximum on-resistance specified for the PSMUX154ZMEX?

The maximum on-resistance is 6.5Ω, measured at VDD = 3.0V with an input voltage between 0V and 0.4V and a current of -40mA.

How does the PSMUX154ZMEX handle switching transitions?

It employs break-before-make switching, which ensures that both switches are not enabled simultaneously, thereby eliminating signal disruption during switching events.
