Octal D-Type Latch
MM54C374/MM74C374 TRI-STATE Octal D-Type Flip-Flop
General Description
The MM54C373/MM74C373, MM54C374/MM74C374 are
integrated, complementary MOS (CMOS), 8-bit storage ele-
ments with TRI-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 ap-
plied 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 MM54C373/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 MM54C374/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 positive-going transitions of the CLOCK input.
Both the MM54C373/MM74C373 and the MM54C374/
MM74C374 are being assembled in 20-pin dual-in-line pack-
ages with 0.300

pin centers.
