HD74HC112 Datasheet Dual J-k Flip-flops

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC112 Dual J-K Flip-Flops (with Preset and Clear).

General Description

Each flip-flop has independent J, K, preset, clear and clock inputs and Q and Q outputs.

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

Clear and preset are independent of the clock and accomplished by a low logic level on the corresponding input.

Key Features

  • High Speed Operation: tpd (Clock to Q) = 17 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 L H H H H H H H Note: Clear H L L H H H H H H H L H Clock X X X J X X X L L H H X X X K X X X L H L H X X X Output Q H L H.
