SN74AHCT540NSR TI Buffer/Driver | 20-SO | 8-Ch, Inverting, 4.5V-5.5V

Product Overview

The SN74AHCT540NSR is a high-speed octal buffer and line driver from Texas Instruments, designed with inverting outputs and 3-state outputs for bus-oriented applications. It operates over a supply voltage range of 4.5V to 5.5V, making it ideal for 5V systems. The device features 8-bit wide data paths with inverted outputs, providing high drive capability while maintaining low power consumption. Housed in a 20-pin SO package (NSR suffix), it is suitable for surface-mount assembly and space-constrained designs.
