HD74HC113 Datasheet Dual J-K Flip-Flops

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC113 Dual J-K Flip-Flops (with Preset).

General Description

This flip-flop is edge sensitive to the clock input and change state on the negative going transition of the clock pulse.

Each one has independent J, K, clock, and preset inputs and Q and Q inputs.

Preset is independent of the clock and accomplished by a low level on the input.

Key Features

  • High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 2 µA max (Ta = 25°C) Function Table Inputs Preset L H H H H H H H H L Clock X J X L L H H X X X K X L H L H X X X Output Q H No change L H Toggle No change No change No change H L Q L HD74HC113 Pin Arrangement 1CK 1K 1J 1PR 1.
