Description
The ’HC173 and ’HCT173 high speed three-state quad D-
type flip-flops are fabricated with silicon gate CMOS technol-
ogy. They possess the low power consumption of standard
CMOS Integrated circuits, and can operate at speeds com-
parable to the equivalent low power Schottky devices. The
buffered outputs can drive 15 LSTTL loads. The large output
drive capability and three-state feature make these parts ide-
ally suited for interfacing with bus lines in bus oriented sys-
tems.
The four D-type flip-flops operate synchronously from a com-
mon clock. The outputs are in the three-state mode when
either of the two output disable pins are at the logic “1” level.
The input ENABLES allow the flip-flops to remain in their
present states without having to disrupt the clock If either of
the 2 input ENABLES are taken to a logic “1” level, the Q
outputs are fed back to the inputs, forcing the flip-flops to
remain in the same state. Reset is enabled by taking the
MASTER RESET (MR) input to a logic “1” level. The data
outputs change state on the positive going edge of the clock.
The ’HCT173 logic family is functionally, as well as pin com-
patible with the standard LS logic family
