SN74HC540NS TI Octal Buffer/Line Driver | 20-SO | 2V to 6V, 8 Channels

Product Overview

The SN74HC540NS from Texas Instruments is a high-performance octal buffer and line driver designed for 2V to 6V VCC operation. It features 8 non-inverting channels with 3-state outputs, making it ideal for bus-oriented applications. Housed in a 20-pin SO package (NS suffix), this device offers high noise immunity and low power consumption, characteristic of the HC family. The SN74HC540NS is a direct replacement for the SN74HC540 in SO packages, providing enhanced thermal performance and reduced footprint.
