CD74HCT253中文资料高速 CMOS 逻辑双路 4 输入多路复用器数据手册TI规格书

描述 Description

The CD74HC253 and CD74HCT253 are dual 4-to-1 line selector/multiplexers having three-state outputs. One of four sources for each section is selected by the common select inputs, S0 and S1. When the output enable (1OE\\, 2OE\\) is HIGH, the output is in the high-impedance state.
