SN74HC125DT TI Quad Bus Buffer Gate | 14-SOIC | 2V to 6V, 3-State Outputs

Product Overview

The SN74HC125DT from Texas Instruments is a high-speed quad bus buffer gate with 3-state outputs, designed for 2V to 6V VCC operation. Housed in a compact 14-SOIC package, it features four independent buffer gates with active-low output enable (OE) inputs. When OE is low, the output is enabled; when high, the output is in a high-impedance state, allowing multiple outputs to share a bus line. This device is ideal for driving bus lines or buffering memory address registers, offering low power consumption and high noise immunity characteristic of CMOS technology.
