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.
