DM74AS240 Datasheet 3-state Bus Driver/receiver

Manufacturer: Fairchild (now onsemi)

Overview: DM74AS240 • DM74AS244 3-STATE Bus Driver/Receiver October 1986 Revised March 2000 DM74AS240 • DM74AS244 3-STATE Bus.

General Description

This family of Advance Schottky 3-STATE Bus circuits are designed to provide either bidirectional or unidirectional buffer interface in Memory, Microprocessor, and munication Systems.

The output characteristics of the circuits have low impedance sufficient to drive terminated transmission lines down to 133Ω.

The input characteristics of the circuits likewise have a high impedance so it will not significantly load the transmission line.

Key Features

  • s Advanced oxide-isolated, ion-implanted Schottky TTL process s Improved switching performance with less power dissipation compared with Schottky counterpart s Functional and pin compatible with 74LS and Schottky counterpart s Switching response specified into 500Ω and 50 pF s Specified to interface with CMOS at VOH = VCC.
  • 2V Ordering Code: Order Number DM74AS240WM DM74AS240N DM74AS244WM DM74AS244N Package Number M20B N20A M20B N20A Package.
