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
