SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
The MC74HC125A and MC74HC126A are identical in pinout to the LS125  
and LS126. The device inputs are compatible with standard CMOS outputs;  
with pullup resistors, they are compatible with LSTTL outputs.  
The HC125A and HC126A noninverting buffers are designed to be used  
with 3–state memory address drivers, clock drivers, and other bus–oriented  
systems. The devices have four separate output enables that are active–low  
(HC125A) or active–high (HC126A).
