DM74ALS240AWM

Buffers, Drivers, Receivers, Transceivers Overview

The DM74ALS240AWM is an octal 3-STATE bus driver manufactured by onsemi, utilizing the Advanced Low Power Oxide-isolated Ion-implanted Schottky (ALS) TTL process. It operates within a supply voltage range of 4.5V to 5.5V and supports a free-air operating temperature from 0°C to +70°C. The device features low level drive current capability of 24mA and includes PNP input design to reduce input loading. It provides flexible bus interface implementation for memory, microprocessor, or communication systems with outputs organized into two separate groups of four buffers.
