Description

The 74LS245 Octal Tri-State Transceiver is designed for asynchronous two-way communication between data buses. The control-function implementation reduces the need for external timing.

Based on the logic level at the direction control (DIR) input, the device allows data transmission from the A Bus to the B Bus or from the B Bus to the A Bus.

The enable input (G) can be used to disable the device and effectively isolate the buses.

Features

  • Bi-Directional bus transceiver in a high-density 20-pin package.
  • 3-STATE outputs drive bus lines directly
  • PNP inputs reduce DC loading on bus lines
  • Hysteresis at bus inputs improves noise margins
  • Typical propagation delay times, port-to-port 8ns
  • Typical enable/disable times 17ns
