SN74LS540N TI Buffer/Driver | 20-PDIP | Inverting, 3-State, 8-Channel

Product Overview

The SN74LS540N is a high-performance octal buffer and line driver from Texas Instruments, designed with inverting outputs and 3-state capability. Housed in a 20-pin PDIP package, this device features eight independent buffers with common output enable controls. It is ideal for driving bus lines or buffering memory address registers, offering high noise immunity and low power consumption typical of LS logic families.
