SN74HCT125DT TI Buffer/Driver | 14-SOIC | 4.5V-5.5V, 4-Channel

Product Overview

The SN74HCT125DT is a high-speed CMOS quad bus buffer gate with 3-state outputs from Texas Instruments. It operates from a 4.5V to 5.5V supply voltage and is designed to drive bus lines or buffer memory address registers. The device features four independent buffers with non-inverting outputs, each controlled by an output enable (OE) input. When OE is low, the output is enabled; when high, the output is in high-impedance state. This device is ideal for interfacing with TTL logic levels and is compatible with LSTTL.
