Quad D-Type Flip-Flop, Three-State February 1998 -Revised October 2003 Features Description Three-State Buffered Outputs The ’HC173 and ’HCT173 high speed three-state quad Dtype flip-flops are fabricated with silicon gate CMOS technology. They possess the low power consumption of standard
CMOS Integrated circuits, and can operate at speeds comparable 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 ideally suited for interfacing with bus lines in bus oriented systems. Gated Input and Output Enables Fanout (Over Temperature Range)
-Standard Outputs . 10 LSTTL Loads
-Bus Driver Outputs . 15 LSTTL Loads Wide Operating Temperature Range . -55oC to 125oC Balanced Propagation Delay and Transition Times Significant Power Reduction Compared to LSTTL
Logic ICs The four D-type flip-flops operate synchronously from a common 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 …
