Flip-Flops with Clear
General Description
These edge triggered flip-flops utilize advanced silicon-gate
CMOS technology to implement D-type flip-flops They pos-
sess high noise immunity low power and speeds compara-
ble to low power Schottky TTL circuits This device contains
8 master-slave flip-flops with a common clock and common
clear Data on the D input having the specified setup and
hold times is transferred to the Q output on the low to high
transition of the CLOCK input The CLEAR input when low
sets all outputs to a low state
Each output can drive 10 low power Schottky TTL equiva-
lent loads The MM54HC273MM74HC273 is functionally
as well as pin compatible to the 54LS27374LS273 All in-
puts are protected from damage due to static discharge by
diodes to VCC and ground
