SN74ACT125PWR TI Buffer/Driver | 14-TSSOP | 4.5V-5.5V, 24mA

Product Overview

The SN74ACT125PWR is a quad bus buffer gate with 3-state outputs from Texas Instruments, designed for 4.5V to 5.5V VCC operation. It features four independent buffer gates with non-inverting outputs, each with its own output enable input (active low). The device is fabricated using advanced CMOS technology to achieve high speed and low power consumption, making it suitable for driving bus lines or buffering memory address registers. The 3-state outputs allow connection to a bus-oriented system without loading the bus when disabled. The SN74ACT125PWR is available in a 14-pin TSSOP package, offering a compact footprint for space-constrained applications.
