8-Channel 3-STATE Multiplexer  
to the Y and W outputs. The 74HC logic family is speed,  
function, as well as pinout compatible with the standard  
74LS logic family. All inputs are protected from damage  
due to static discharge by internal diode clamps to VCC and  
General Description  
The MM74HC251 8-channel digital multiplexer with 3-  
STATE outputs utilizes advanced silicon-gate CMOS tech-  
nology. Along with the high noise immunity and low power  
consumption of standard CMOS integrated circuits, it pos-  
sesses the ability to drive 10 LS-TTL loads. The large out-  
put drive capability and 3-STATE feature make this part  
ground.  
Features  
Typical propagation delay  
ideally suited for interfacing with bus lines in a bus oriented  
system.  
Data select to Y: 26 ns  
This multiplexer features both true (Y) and complement  
(W) outputs as well as a STROBE input. The STROBE  
must be at a low logic level to enable this device. When the  
STROBE input is HIGH, both outputs are in the high  
impedance state. When enabled, address information on  
the data select inputs determines which data input is routed  
Wide supply range: 2–6V  
Low power supply quiescent current:  
80 µA maximum (74HC)  
3-STATE outputs for interface to bus oriented  
systems
