The 74LS76 is a digital integrated circuit (IC) containing two independent JK Flip-Flops with individual Set (Preset) and Clear inputs. Utilizing Low-power Schottky (LS) technology, it ensures reliable switching with reduced power dissipation. It is perfectly suited for designing 5V TTL circuits such as counters, frequency dividers, and shift registers, and comes in a convenient Through-Hole DIP-16 package.

 

74LS76 Dual JK Flip-Flop with Set and Clear

The 74LS76 integrated circuit provides two distinct and fully independent JK Flip-Flops. Each flip-flop is equipped with its own J, K, Clock, Preset (Set), and Clear inputs, along with complementary Q and /Q outputs. It serves as a fundamental building block in creating sequential logic circuits and temporarily storing binary data.

Key Features

  • Operating Voltage: Standard operation at 5V (Range: 4.75V to 5.25V).
  • Logic Type: Dual JK Flip-Flop (Negative-Edge Triggered).
  • Technology: Low-power Schottky (LS) for fast switching speeds and minimized power consumption.
  • Frequency: Typical maximum clock frequency of approximately 15MHz - 20MHz.
  • Inputs: Independent Preset (Set) and Clear inputs (Active LOW) to directly control the output state regardless of clock.
  • Mounting Type: Through-Hole, ideal for breadboards and rapid prototyping.

Pinout Overview

The DIP-16 package allocates specific pins for power and flip-flop I/O. Note: This IC has a non-standard power pin placement compared to common TTL chips (like the 7400):

  • Pin 5: VCC (+5V Power Supply)
  • Pin 13: GND (Ground)
  • Pins 1, 6: Clock Inputs (CP) for Flip-Flop 1 and 2 respectively.
  • Pins 4, 16 / 9, 12: J and K Inputs.
  • Pins 2, 7 / 3, 8: Preset (PRE) and Clear (CLR) Inputs (Active LOW).
  • Pins 15, 14 / 11, 10: Outputs Q and /Q.
