SN74AHC126DR TI Buffer/Line Driver | 14-SOIC | 2V to 5.5V, 3-State Outputs

Product Overview

The SN74AHC126DR from Texas Instruments is a high-speed quad bus buffer gate with 3-state outputs, designed for 2V to 5.5V VCC operation. It features four independent buffer gates with output enable (OE) inputs, making it ideal for driving bus lines or buffering memory address registers. The device is fabricated using advanced CMOS technology to achieve high speed while maintaining low power dissipation. Housed in a 14-pin SOIC package, it is suitable for space-constrained applications.
