DESCRIPTION

These quad differential receivers accept digital data

over balanced transmission lines. They translate

differential input logic levels to TTL output logic levels.

The TB5R3 is a pin- and function-compatible

replacement for the Agere systems BRF1A; it

includes 3-kV HBM and 2-kV CDM ESD protection.

The power-down loading characteristics of the

receiver input circuit are approximately 8 kΩ relative

to the power supplies; hence they do not load the

transmission line when the circuit is powered down.

The packaging for this differential line receiver is a

16-pin gull wing SOIC (DW) or a 16 pin SOIC (D).

The enable inputs of this device include internal

pull-up resistors of approximately 40 kΩ that are

connected to VCC to ensure a logical high level input

if the inputs are open circuited.
