MM54C173 MM74C173 TRI-STATE Quad D Flip-Flop

General Description

The MM54C173 MM74C173 TRI-STATE quad D flip-flop is

a monolithic complementary MOS (CMOS) integrated circuit

constructed with N- and P-channel enhancement transis-

tors The four D-type flip-flops operate synchronously from a

common clock The TRI-STATE output allows the device to

be used in bus-organized systems

The outputs are placed in the TRI-STATE mode when either

of the two output disable pins are in the logic ‘‘1’’ level The

input disable allows the flip-flops to remain in their present

states without disrupting the clock If either of the two input

disables are taken to a logic ‘‘1’’ level the Q outputs are fed

back to the inputs and in this manner the flip-flops do not

change state

Clearing is enabled by taking the input to a logic ‘’1’’ level

Clocking occurs on the positive-going transition
