Description

These quad differential receivers accept digital data over balanced transmission lines. They translate differential input logic levels to TTL output logic levels. All devices in this family have four receivers with a common enable control. These receivers are pin equivalent to the general-trade 26LS32, but offer increased speed and decreased power consumption.

They replace the Agere 41 Series receivers.

The BRF1A device is the generic receiver in this family and requires the user to supply external resistors on the circuit board for impedance matching.

The BRF2A is identical to the BRF1A, but has an electrostatic discharge (ESD) protection circuit added to significantly improve the ESD human-body model (HBM) characteristics on the differential input terminals.
