Manufacturer: Texas Instruments

Overview: CD54HC251, CD74HC251, CD54HCT251, CD74HCT251 SCHS169D – NOVEMBER 1998 – REVISED MARCH 2022 CDx4HC251, CDx4HCT251 High-Speed CMOS Logic 8-Input Multiplexer, Three-State.

General Description

The ’HC251 and ’HCT251 are 8-channel digital multiplexers with three-state outputs, fabricated with high-speed silicongate CMOS technology.

Together with the low power consumption of standard CMOS integrated circuits, they possess the ability to drive 10 LSTTL loads.

The three-state
