MM54HC151/MM74HC151 8-Channel
Digital Multiplexer
General Description
This high speed Digital multiplexer utilizes advanced silicongate
CMOS technology. Along with the high noise immunity
and low power dissipation of standard CMOS integrated circuits,
it possesses the ability to drive 10 LS-TTL loads. The
MM54HC151/MM74HC151 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.
The 54HC/74HC logic family is functionally as well as pinout
compatible with the standard 54LS/74LS logic family.
All inputs are protected from damage due to static discharge
by internal diode clamps to VCC and ground.
Features
Y Typical propagation delay
data select to output Y: 26 ns
Y Wide operating supply voltage range: 2±6V
Y Low input current: 1 mA maximum
Y Low quiescent supply current: 80 mA maximum (74HC)
Y High output drive current: 4 mA minimum
