3-STATE Octal D-Type Flip-Flop

General Description

The MM74C373 and MM74C374 are integrated, comple-

mentary MOS (CMOS), 8-bit storage elements with 3-

STATE outputs. These outputs have been specially

designed to drive high capacitive loads, such as one might

find when driving a bus, and to have a fan out of 1 when

driving standard TTL. When a high logic level is applied to

the OUTPUT DISABLE input, all outputs go to a high

impedance state, regardless of what signals are present at

the other inputs and the state of the storage elements.

The MM74C373 is an 8-bit latch. When LATCH ENABLE is

high, the Q outputs will follow the D inputs. When LATCH

ENABLE goes low, data at the D inputs, which meets the

set-up and hold time requirements, will be retained at the

outputs until LATCH ENABLE returns high again.

The MM74C374 is an 8-bit, D-type, positive-edge triggered

flip-flop. Data at the D inputs, meeting the set-up and hold

time requirements, is transferred to the Q outputs on posi-

tive-going transitions of the CLOCK input.

Both the MM74C373 and the MM74C374 are being assem-

bled in 20-pin dual-in-line packages with 0.300” pin cen-

ters.
