74F74D** is a dual D-type flip-flop integrated circuit (IC) manufactured by various semiconductor companies, including **Texas Instruments (TI)**, **Fairchild Semiconductor (now ON Semiconductor)**, and **NXP Semiconductors**.

The 74F74D is a dual D-type flip-flop integrated circuit (IC) manufactured by various semiconductor companies, including Texas Instruments (TI), Fairchild Semiconductor (now ON Semiconductor), and NXP Semiconductors.

Key Specifications:

  • Logic Family: 74F (Fast TTL)
  • Function: Dual D-Type Positive-Edge-Triggered Flip-Flop
  • Number of Flip-Flops: 2
  • Trigger Type: Positive Edge
  • Supply Voltage (VCC): 4.5V to 5.5V (Standard 5V operation)
  • High-Level Input Voltage (VIH): 2.0V (min)
  • Low-Level Input Voltage (VIL): 0.8V (max)
  • High-Level Output Current (IOH): -1 mA
  • Low-Level Output Current (IOL): 20 mA
  • Propagation Delay: ~5 ns (typical)
  • Operating Temperature Range: 0°C to +70°C (Commercial)
  • Package Type: SOIC-14 (74F74D), DIP-14 (74F74N)

Features:

  • Independent Data (D), Clock (CLK), Set (PRE), and Clear (CLR) inputs for each flip-flop
  • Asynchronous Set (PRE) and Clear (CLR) for direct control
  • High-speed operation due to 74F technology
  • TTL-compatible inputs and outputs
  • Wide operating voltage range (4.5V–5.5V)

Applications:

  • Data storage and transfer
  • Synchronous counters
  • Shift registers
  • Frequency division
  • Digital signal processing

The 74F74D is commonly used in digital logic circuits where fast switching and reliable edge-triggered operation are required. The "D" suffix typically indicates an SOIC (Small Outline IC) package. For a DIP (Dual Inline Package) variant, the part number may be 74F74N.

For exact datasheet details, refer to the manufacturer's documentation (e.g., Texas Instruments, ON Semiconductor, or NXP).
