SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
N SUFFIX  
PLASTIC PACKAGE  
CASE 738–03  
The MC74HC299 is identical in pinout to the LS299. The device inputs are  
compatible with standard CMOS outputs; with pullup resistors, they are  
compatible with LSTTL outputs.

The HC299 features a multiplexed parallel input/output data port to  
achieve full 8–bit handling in a 20 pin package. Due to the large output drive  
capability and the 3–state feature, this device is ideally suited for interface  
with bus lines in a bus–oriented system.

data applied to the data port to be clocked into the register. Reading out of  
the register can be accomplished when the outputs are enabled. The  
active–low asynchronous Reset overrides all other inputs.
