74245 - 3-STATE Octal Bus Transceiver

General Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses.

The control function implementation minimizes external timing requirements.

Key Features

  • s Bi-Directional bus transceiver in a high-density 20-pin package s 3-STATE outputs drive bus lines directly s PNP inputs reduce DC loading on bus lines s Hysteresis at bus inputs improve noise margins s Typical propagation delay times, port-to-port 8 ns s Typical enable/disable times 17 ns s IOL (sink current) 24 mA s IOH (source current).
  • 15 mA Ordering Code: Order Number DM74LS245WM DM74LS245SJ DM74LS245N Package Number M20B M20D N20A Package.

DM74LS245 3-STATE Octal Bus Transceiver August 1986 Revised March 2000 DM74LS245 3-STATE Octal Bus Transceiver General Description These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control function implementation minimizes external timing requirements. The device allows data transmission from the A Bus to the B Bus or from the B Bus to the A Bus depending upon the logic level at the direction control (DIR) input. The enable input (G) can be used to disable the device so that the buses are effectively isolated.
