SN74ABT125DR is a quad bus buffer gate manufactured by Texas Instruments.

The SN74ABT125DR is a quad bus buffer gate manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

Specifications:

  • Technology Family: ABT
  • Supply Voltage Range: 4.5V to 5.5V
  • Number of Channels: 4
  • Output Type: 3-State
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: SOIC (DR)
  • Package Size: 14-pin
  • Propagation Delay (Max): 4.5ns at 5V
  • Input Logic Level - Low (Max): 0.8V
  • Input Logic Level - High (Min): 2V
  • Output Current (High/Low): ±32mA

Description:

The SN74ABT125DR is a high-speed, low-power quad bus buffer gate with 3-state outputs. It is designed for driving heavily loaded bus lines or memory address registers while maintaining high-speed operation. The device features independent output-enable (OE) inputs for each buffer, allowing for flexible control.

Features:

  • 4-bit bus buffer with 3-state outputs
  • High-drive outputs (-32mA IOH, 64mA IOL)
  • BiCMOS technology for low power consumption
  • Latch-up performance exceeds 500mA per JESD 17
  • ESD protection exceeds 2000V per MIL-STD-883, Method 3015
  • Flow-through pinout for optimized PCB layout
  • Compatible with TTL input and output levels

This device is commonly used in applications such as bus interfacing, memory address buffering, and general-purpose logic buffering.
