SN74CBT3257CPWRG4 Description

Short technical summary and product information.

The Texas Instruments SN74CBT3257CPWRG4 is a high-speed, TTL-compatible FET multiplexer/demultiplexer. It features 4 independent 2:1 channels, enabling bidirectional data flow with near-zero propagation delay.

 

This device offers robust performance with low ON-state resistance and low input/output capacitance. It includes undershoot protection on its A and B ports, safeguarding against voltage dips up to -2V. The operating voltage range is from 4.5V to 5.5V, and it supports signaling levels from 0V to 5V. Control inputs are compatible with TTL or 5V/3.3V CMOS logic.

 

Designed for versatility, the SN74CBT3257CPWRG4 supports both digital and analog applications, including USB interfaces and bus isolation. It operates within an ambient temperature range of -40°C to 85°C. The component is supplied in a 16-TSSOP surface-mount package, with a standard package quantity of 2000 units on tape and reel.
