CD74HCT4067数据手册TI中文资料规格书

描述 Description

The CD74HC4067 and CD74HCT4067 devices are digitally controlled analog switches that utilize silicon-gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.

These analog multiplexers/demultiplexers control analog voltages that may vary across the voltage supply range. They are bidirectional switches thus allowing any analog input to be used as an output and vice-versa. The switches have low \"on\" resistance and low \"off\" leakages. In addition, these devices have an enable control which when high will disable all switches to their \"off\" state.
