CD74HC4067-Q1中文资料汽车级 5V 16:1 单通道模拟多路复用器数据手册TI规格书

描述 Description

The CD74HCx4067-Q1 device is a digitally controlled analog switch that utilizes silicon-gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.

This analog multiplexer and demultiplexer controls analog voltages that may vary across the voltage supply range. It is a bidirectional switch, thus allowing any analog input to be used as an output and vice-versa. The switch has low (on) resistance and low (off) leakages. In addition, the device has an enable control that, when high, disables all switches to their off state.
