inputs. This eliminates the need for an external
鈩?/div>
impedance line.
This device is designed to work with the DP1A or
PNPA in point-to-point applications.
The BRT1A is equivalent to the BRF1A; however, it
is provided with a Y-type resistor network across the
differential inputs and terminated to ground. The
Y-type termination provides the best EMI results.
This device is not recommended for applications
where the differences in ground voltage between the
driver and the receiver exceed 1 V. This device is
designed to work with the DG1A or PNGA in point-to-
point applications.
The powerdown loading characteristics of the
receiver input circuit are approximately 8 k鈩?relative
to the power supplies; hence, they will not load the
transmission line when the circuit is powered down.
For those circuits with termination resistors, the line
will remain impedance matched when the circuit is
powered down.
The packaging options that are available for these
quad differential line drivers include a 16-pin DIP; a
16-pin, J-lead SOJ; a 16-pin, gull-wing small-outline
integrated circuit (SOIC); and a 16-pin, narrow-body,
gull-wing SOIC.

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.
* This feature is available on BRF1A and BRF2A.
