SN74ALS540DWR TI Buffer/Driver | 20-SOIC | 8-Ch, Inverting, 3-State

Product Overview

The SN74ALS540DWR from Texas Instruments is an octal buffer and line driver designed for high-performance memory and bus-oriented systems. It features 8-bit inverting outputs with 3-state capability, allowing for efficient data flow control. Housed in a 20-pin SOIC package, this device operates from a 4.5V to 5.5V supply and offers high drive current (up to 24 mA sink/15 mA source) while maintaining low power consumption. The SN74ALS540DWR is ideal for driving heavily loaded buses and is compatible with TTL logic levels.
