The MM54C373 MM74C373 MM54C374 MM74C374 are integrated complementary MOS (CMOS) 8-bit storage elements 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 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 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
