CD74AC253数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The CD74AC253 and ’ACT253 dual 4-input multiplexers that utilize Advanced CMOS Logic technology. One of the four sources for each section is selected by the common Select inputs, S0 and S1. When the Output Enable (1OE\\ or 2OE\\) is HIGH, the output is in the high-impedance state.
