Product specification
Dual JK flip-flop with reset; negative-edge trigger
74HC/HCT73
The 74HC/HCT73 are dual negative-edge triggered
FEATURES
JK-type flip-flops featuring individual J, K, clock (nCP) and
reset (nR) inputs; also complementary Q and Q outputs.
• Output capability: standard
• ICC category: flip-flops
The J and K inputs must be stable one set-up time prior to
the HIGH-to-LOW clock transition for predictable
operation.
GENERAL DESCRIPTION
The 74HC/HCT73 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The reset (nR) is an asynchronous active LOW input.
When LOW, it overrides the clock and data inputs, forcing
the Q output LOW and the Q output HIGH.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V
