Features  
Description  
• Selects One of Eight Binary Data Inputs  
• Three-State Output Capability  
• True and Complement Outputs  
The ’HC251 and ’HCT251 are 8-channel digital multiplexers  
with three-state outputs, fabricated with high-speed silicon-  
gate 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  
feature makes them ideally suited for interfacing with bus  
lines in a bus-oriented system.

• Balanced Propagation Delay and Transition Times  
When enabled, address information on the data select inputs  
determines which data input is routed to the Y and Y  
outputs. The ’HCT251 logic family is speed, function, and  
pin-compatible with the standard ’LS251.
