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
Features
Y Typical propagation delay 20 ns
Y Low quiescent supply current 40 mA maximum
(74HCT Series)
Y Low input current 1 mA maximum
Y Fanout of 10 LS-TTL loads
Y TTL input compatible
