P82B96

SCPS144C – MAY 2006 – REVISED MAY 2015

1 Features

3 Description

The P82B96 device is a bus buffer that supports

1

•

Operating Power-Supply Voltage Range

of 2 V to 15 V

range of other bus configurations with different

•

voltage and current levels.

Different Logic Levels (2 V to 15 V)

One of the advantages of the P82B96 is that it

•

Longer Cables by allowing bus capacitance of

supports longer cables/traces and allows for more

400 pF on Main Side (Sx/Sy) and 4000 pF on

Transmission Side (Tx/Ty)

capacitance such that the total loading (devices and

•

Outputs on the Transmission Side (Tx/Ty) Have

High Current Sink Capability for Driving Low-

Impedance or High-Capacitive Buses

due to capacitance, or the physical separation

•

Interface With Optoelectrical Isolators and Similar

between them, are greatly improved.

Devices That Need Unidirectional Input and

The device is able to provide galvanic isolation

(optocoupling) or use balanced transmission lines

Into Pairs of Forward (Tx/Ty) and Reverse (Rx/Ry)

(twisted pairs), because separate directional Tx and

Signals

Rx signals are provided. The Tx and Rx signals may

be connected directly (without causing bus latching),

properties (open-drain driver). Likewise, the Ty and

Ry signals may also be connected together to provide
