Flip-Flop General Description 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 The MM54C374 MM74C374 is an 8-bit D-type positiveedge 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 packages with 0 300 pin centers Features Y Y Y Y Wide supply voltage range High noise immunity Low power consumption TTL compatibility 3V to 15V 0 45 VCC (typ ) Fan out of 1 driving standard TTL Y Y Y Y Y Bus driving capability TRI-STATE outputs Eight storage elements in one package Single CLOCK LATCH ENABLE and OUTPUT DISABLE control inputs 20-pin dual-in-line package with 0 300 centers takes half the board space of a 24-pin package Connection Diagrams MM54C373
