SN74AHC244DWR TI Buffer/Line Driver | 20-SOIC | 8-Ch, Non-Inverting, 2V to 5.5V

Product Overview

The SN74AHC244DWR from Texas Instruments is a high-speed octal buffer and line driver designed for 2-V to 5.5-V VCC operation. It features eight non-inverting buffers with three-state outputs, making it ideal for driving bus lines or buffering memory address registers. The device is fabricated using advanced CMOS technology to achieve high speed while maintaining low power dissipation. The inputs are tolerant to 5.5 V, allowing for mixed-voltage system compatibility. The SN74AHC244DWR is offered in a 20-pin SOIC package (DWR) and is characterized for operation from -40°C to +125°C.
