MM54HCT253中文资料Dual 4-Channel TRI-STATE® Multiplexer数据手册TI规格书

描述 Description

General Description
The MM54HCT253/MM74HCT253 utilizes advanced silicon-gate CMOS technology to achieve the low power consumption of standard CMOS integrated circuits, along with the capability to drive 10 LS-TTL loads. The large output drive and TRI-STATE features of this device make it ideally suited for interfacing with bus lines in bus organized systems. When the output control input is taken high, the multiplexer outputs are sent into a high impedance state.
