The TB5T1 device is a dual differential driver/receiver circuit that transmits and receives digital data over balanced transmission lines. The dual drivers translate input TTL logic levels to differential pseudo-ECL output levels. The dual receivers convert differential-input logic levels to TTL output levels. Each driver or receiver pair has its own common enable control allowing serial data and a control clock to be transmitted and received on a single integrated circuit. The TB5T1 requires the customer to supply termination resistors on the circuit board.

The power-down loading characteristics of the receiver input circuit are approximately 8 k relative to the power supplies; hence, it does not load the transmission line when the circuit is powered down.

In circuits with termination resistors, the line remains impedance- matched when the circuit is powered down. The driver does not load the line when it is powered down.

All devices are characterized for operation from -40°C to 85°C.

The logic inputs of this device include internal pull-up resistors of approximately 40 k that are connected to VCC to ensure a logical high level input if the inputs are open circuited.
