Quad D-Type Flip-Flop, Three-State

Features

Description

• Three-State Buffered Outputs

• Gated Input and Output Enables

The Harris CD74HC173 and CD74HCT173 high speed

three-state quad D-type ﬂip-ﬂops are fabricated with silicon

gate CMOS technology. They possess the low power con-

sumption 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 fea-

ture make these parts ideally suited for interfacing with bus

lines in bus oriented systems.

• Fanout (Over Temperature Range)

- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads

- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

• Signiﬁcant Power Reduction Compared to LSTTL

Logic ICs

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.

• HC Types

- 2V to 6V Operation

- High Noise Immunity: N = 30%, N = 30% of V
