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
