TB5R3,pdf(Quad Differential PE

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 k 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 k that are connected to V_CC to ensure a logical high level input if the inputs are open circuited.
