74HC73

Dual JK ﬂip-ﬂop with reset; negative-edge trigger

Rev. 03 — 12 November 2004

Product data sheet

1. General description

The 74HC73 is a high-speed Si-gate CMOS device and is pin compatible with low-power

Schottky TTL (LSTTL). The 74HC73 is speciﬁed in compliance with JEDEC

standard no. 7A.

The 74HC is a dual negative-edge triggered JK ﬂip-ﬂop featuring individual J, K, clock

(nCP) and reset (nR) inputs; also complementary nQ and nQ outputs.

The J and K inputs must be stable one set-up time prior to the HIGH-to-LOW clock

transition for predictable operation.

The reset (nR) is an asynchronous active LOW input. When LOW, it overrides the clock

and data inputs, forcing the nQ output LOW and the nQ output HIGH.

Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock

rise and fall times.

2. Features

■ Low-power dissipation

■ Complies with JEDEC standard no. 7A

■ ESD protection:

◆ HBM EIA/JESD22-A114-B exceeds 2000 V

◆ MM EIA/JESD22-A115-A exceeds 200 V.

■ Multiple package options

■ Speciﬁed from −40 °C to +80 °C and from −40 °C to +125 °C.
