SN74AHC244NS TI Buffer/Line Driver | 20-SO | 8-Ch, Non-Inverting, 2V-5.5V

Product Overview

The SN74AHC244NS is a high-performance octal buffer and line driver designed by Texas Instruments (TI) to drive bus lines or buffer memory address registers. It features non-inverting outputs with three-state capability, making it ideal for multiplexed data transmission or memory interface applications. Housed in a 20-pin SO package, this device operates over a wide supply voltage range of 2V to 5.5V, ensuring compatibility with both 3.3V and 5V logic systems. Its advanced silicon-gate CMOS technology achieves high speed while maintaining low power dissipation, typical of AHC family devices.
