  • High-Level Output Current (IOH): -0.4mA
  • Low-Level Output Current (IOL): 8mA
  • Propagation Delay (tpd): Typically 15ns
  • Operating Temperature Range: 0°C to +70°C
  • Package Type: DIP-14 (Dual In-Line Package, 14 pins)

Descriptions:

The T74LS125AB1 is a quad tri-state buffer designed for bus-oriented applications. It features four independent buffers, each with a control input that enables or disables the output in a high-impedance state.

Features:

  • Tri-State Outputs: Allows multiple devices to share a common bus without interference.
  • TTL-Compatible Inputs: Ensures compatibility with standard TTL logic levels.
  • Low Power Consumption: LS technology reduces power dissipation.
  • High Noise Immunity: Provides reliable operation in noisy environments.
  • Wide Operating Voltage Range: Supports standard 5V logic systems.

This part is commonly used in digital systems for signal buffering, bus driving, and interfacing applications.
