SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

J SUFFIX

CERAMIC PACKAGE

CASE 732–03

The MC54/74HC273A is identical in pinout to the LS273. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LSTTL outputs.

This device consists of eight D flip–flops with common Clock and Reset

inputs. Each flip–flop is loaded with a low–to–high transition of the Clock

input. Reset is asynchronous and active low.
