SN74AHC125QDR TI Buffer/Driver | 14-SOIC | 2V to 5.5V, 3-State Outputs

Product Overview

The SN74AHC125QDR is a quad bus buffer gate with 3-state outputs from Texas Instruments, designed for 2-V to 5.5-V VCC operation. It features independent line drivers with 3-state outputs, making it ideal for driving bus lines or buffer memory address registers. The device is fabricated using advanced CMOS technology to achieve high speed while maintaining low power dissipation. The 3-state control gate operates as a two-input AND: when the output-enable (OE) input is low, the output is disabled (high-impedance state); when OE is high, the output is enabled. The SN74AHC125QDR is offered in a 14-pin SOIC package and is fully specified for partial-power-down applications using Ioff circuitry, which prevents damaging current backflow when the device is powered down.
