Overview

Description

The QS33X257 is a high-speed CMOS TTL-compatible 24:12 multiplexer/ demultiplexer. The QS33X257 is functionally compatible to three of the QuickSwitch version of the 74F257, 74FCT257, and the 74ALS/AS/ LS257 Quad 2:1 multiplexers. The low ON resistance of the QS33X257 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS33X257 operates at -40C to +85C.

Features
