General Description
The MM54C373MM74C373 MM54C374MM74C374 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 MM54C373MM74C373 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 MM54C374MM74C374 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 MM54C373MM74C373 and the MM54C374
MM74C374 are being assembled in 20-pin dual-in-line pack-
ages with 0300
pin centers
