HD74HC112P** is a dual negative-edge-triggered JK flip-flop integrated circuit manufactured by **HIT (Hitachi)**.

The HD74HC112P is a dual negative-edge-triggered JK flip-flop integrated circuit manufactured by HIT (Hitachi). Below are its specifications, descriptions, and features:

Specifications:

  • Manufacturer: HIT (Hitachi)
  • Series: 74HC
  • Technology: High-Speed CMOS (HC)
  • Package: DIP-16 (Plastic Dual In-Line Package)
  • Supply Voltage Range: 2V to 6V
  • Operating Temperature Range: -40°C to +85°C
  • High-Level Input Voltage (VIH): 3.15V (min) @ VCC = 4.5V
  • Low-Level Input Voltage (VIL): 1.35V (max) @ VCC = 4.5V
  • Propagation Delay: 20ns (typ) @ VCC = 5V, CL = 50pF
  • Output Current (IO): ±5.2mA @ VCC = 4.5V

Descriptions:

  • The HD74HC112P contains two independent JK flip-flops with individual J, K, Clock (CLK), Preset (PR), and Clear (CLR) inputs.
  • Each flip-flop changes state on the negative (falling) edge of the clock pulse.
  • Asynchronous preset (PR) and clear (CLR) inputs override the clock and data inputs.
  • Suitable for counters, registers, and control applications in digital circuits.

Features:

  • Dual JK Flip-Flops in a single IC
  • Negative-Edge Triggered clock input
  • Asynchronous Preset and Clear for direct control
  • Wide Operating Voltage Range (2V to 6V)
  • Low Power Consumption (typical CMOS power dissipation)
  • High Noise Immunity
  • Compatible with TTL Inputs

This IC is commonly used in sequential logic circuits, frequency division, and data storage applications.
