MM54HCT151/MM74HCT151
8-Channel Digital Multiplexer
General Description
This high speed Digital multiplexer utilizes advanced silicon-
gate CMOS technology. Along with the high noise immunity
and low power dissipation of standard CMOS integrated cir-
cuits, it possesses the ability to drive 10 LS-TTL loads. The
MM54HCT151/MM74HCT151 selects one of the 8 data
sources, depending on the address presented on the A, B,
and C inputs. It features both true (Y) and complement (W)
outputs. The STROBE input must be at a low logic level to
enable this multiplexer. A high logic level at the STROBE
forces the W output high and the Y output low.
MM54HCT/MM74HCT devices are intended to interface be-
tween TTL and NMOS components and standard CMOS
devices. These parts are also plug-in replacements for LS-
TTL devices and can be used to reduce power consumption
in existing designs.
