PI3A268CZMEX

Overview

The PI3A268CZMEX is a dual, fast single-pole double throw (SPDT) CMOS analog switch manufactured by Diodes Incorporated. It operates within a VDD range of 2.5V to 4.2V and supports input signals from -1.5V up to VDD without distortion, making it suitable for AC coupled audio applications. The device features an on-resistance as low as 0.6Ω at 4.2V, with a maximum turn-on/turn-off time of 85ns and off-isolation of -80dB at 100kHz. Packaged in a 10-contact UQFN (1.4 × 1.8mm), it includes break-before-make switching to prevent signal disruption.

Feature Summary

Supports negative input signals down to -1.5V without requiring a negative power supply
Incorporates break-before-make switching logic to eliminate simultaneous switch activation
Provides high off-isolation and crosstalk rejection to reduce signal distortion

Applications

Speaker headset switching
Audio and video signal routing
Power routing
Relay replacement

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging details. The 'X' suffix indicates tape and reel packaging. Confirm RoHS compliance status and ensure the component meets environmental directives relevant to your manufacturing region before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require handling AC coupled audio signals with DC offsets. Ensure the operating voltage remains between 2.5V and 4.2V. Verify that the required on-resistance and bandwidth specifications align with the signal integrity requirements of the target application.

Part Context

This part belongs to the PI3A268 family of dual SPDT analog switches. It utilizes CMOS technology designed for bus and analog applications. The ZM package code corresponds to the 10-contact Ultra-thin Quad Flat No-Lead form factor, providing a compact solution for portable electronic devices.
