SN74HCT125D TI Buffer/Line Driver | 14-SOIC | 4.5V-5.5V, 3-State Outputs

Product Overview

The SN74HCT125D 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, making it compatible with TTL logic levels. The device features four independent buffer gates with non-inverting outputs, each with its own output enable input (active low). When the output enable (OE) input is high, the output is in the high-impedance state. The SN74HCT125D is designed for driving bus lines or buffer memory address registers, and it is ideal for applications requiring high noise immunity and low power consumption.
