SN74LS74AN is a dual D-type positive-edge-triggered flip-flop with preset and clear, manufactured by Texas Instruments (TI) and Motorola (MOT).

The SN74LS74AN is a dual D-type positive-edge-triggered flip-flop with preset and clear, manufactured by Texas Instruments (TI) and Motorola (MOT).

Specifications:

  • Logic Family: 74LS
  • Function: Dual D-Type Flip-flop
  • Trigger Type: Positive-edge-triggered
  • Supply Voltage (VCC): 4.75V to 5.25V
  • Operating Temperature Range: 0°C to 70°C
  • Propagation Delay (Max): 25 ns
  • Output Current (High/Low): -0.4mA / 8mA
  • Package: 14-pin PDIP (Plastic Dual In-Line Package)

Descriptions:

  • Contains two independent D-type flip-flops with individual data (D), clock (CLK), preset (PRE), and clear (CLR) inputs.
  • Outputs include Q and complementary Q̅ for each flip-flop.
  • Preset and clear inputs are asynchronous and active-low.

Features:

  • Edge-Triggered Clocking: Changes state on the positive-going edge of the clock pulse.
  • Asynchronous Clear and Preset: Allows immediate setting or resetting of outputs.
  • Wide Operating Voltage: Compatible with standard TTL levels.
  • High Noise Immunity: Typical of the 74LS series.

This information is based on manufacturer datasheets from TI and Motorola.
