LS1240 Datasheet Octal 3-state Bus Driver

Manufacturer: Fairchild (now onsemi)

Overview: DM74ALS1240A Octal 3-STATE Bus Driver September 1986 Revised February 2000 DM74ALS1240A Octal 3-STATE Bus.

General Description

These octal 3-STATE bus drivers are designed to provide the designer with flexibility in implementing a bus interface with memory, microprocessor, or munication systems, and are low power dissipation versions of the DM74ALS240A and DM74ALS241A.

The output 3-STATE gating control is organized into two separate groups of four buffers.

The DM74ALS1240A control inputs symmetrically enable the respective outputs when set logic LOW.

Key Features

  • s Advanced oxide-isolated, ion-implanted Schottky TTL process s Switching response specified into 500Ω and 50 pF load s Switching response specifications guaranteed over full temperature and VCC supply range s PNP input design reduces input loading s Low power dissipation version s Low level drive current: 74ALS = 16 mA Ordering Code: Order Number DM74ALS1240AWM Package Number M20B Package.
