Product Overview
The SN74ALS540-1NSR is a high-performance octal buffer and line driver from Texas Instruments, designed with inverting outputs and 3-state outputs. It operates from a 4.5V to 5.5V supply and features advanced low-power Schottky (ALS) technology for high speed and low power consumption. The device is ideal for driving bus lines or buffering memory address registers. Its 3-state outputs allow connection to a common bus, and the inverting function provides signal inversion when needed. The SN74ALS540-1NSR is offered in a 20-pin SO package, making it suitable for space-constrained applications.
