SN74AHC126D TI Buffer/Driver | 14-SOIC | 2V-5.5V, 3-State Outputs

Product Overview

The SN74AHC126D is a quadruple 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 buffering memory address registers. The device is fabricated using advanced silicon-gate CMOS technology to achieve high speed and low power consumption, with a typical propagation delay of 4.5 ns at 5 V. The 3-state outputs are controlled by an output-enable (OE) input, allowing connection to a bus-organized system without loading the bus when disabled.
