Description

The BTF1A device is a dual differential transceiver circuit that transmits and receives digital data over balanced transmission lines and is compatible with Lucent Technologies Microelectronics Group differential drivers and receivers. It is designed to provide a strong logic zero when in the third state.

Features

Driver Features

■ Produces a logic zero in third state

■ 400 mV difference voltage in third state

■ Two line drivers per package

■ Logic to convert TTL input logic levels to differential, pseudo-emmiter coupled logic (ECL) output logic levels

■ No line loading when VCC = 0 V

■ High output driver for 50 ? loads

■ 200 mA short-circuit current (typical)

■ 2.0 ns maximum propagation delay

■

Receiver Features

■ Two line receivers per package

■ High input impedance ? 8 k?

■ Logic that converts differential input logic levels to TTL output logic levels

■ 4.0 ns maximum propagation delay

■ <0.20 V input sensitivity (typical)

■ ?1.2 V to +7.2 V common-mode range

Common Device Features

■ Common enable for each driver/receiver pair

■ Operating temperature range: –40 °C to +125 °C (wider than the 41 Series)

■ Single 5.0 V ± 5 supply

■ 400 Mbits/s maximum data rate

■ Meets enhanced small device interface (ESDI) standards

■ Electrostatic discharge (ESD) performance better than the 41 Series

■ Lower power requirement than the 41 Series
