FB2041 - 7-bit Futurebus transceiver

General Description

The FB2041 is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus.

The FB2041 is an inverting transceiver.

The B-port drivers are Low-capacitance open collectors with controlled ramp and are designed to sink 100mA.

Key Features

  • 7-bit BTL transceiver.
  • Separate I/O on TTL A-port.
  • Inverting.
  • Three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit arrangement.
  • Drives heavily loaded backplanes with equivalent load impedances down to 10Ω.
  • High drive 100mA BTL open collector drivers on B-port QUICK.

INTEGRATED CIRCUITS FB2041 7-bit Futurebus+ transceiver Product specification IC19 Data Handbook 1995 May 25 Philips Semiconductors Philips Semiconductors Product specification 7-bit Futurebus+ transceiver FB2041 DESCRIPTION The FB2041 is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The FB2041 is an inverting transceiver. The B-port drivers are Low-capacitance open collectors with controlled ramp and are designed to sink 100mA. Precision band gap references on the B-port insure very good noise margins by limiting the switching threshold to a narrow region centered at 1.55V.
