DESCRIPTION

The SN65HVD96 is specifically designed to meet the requirements for a transceiver which operates with no

errors if the twisted-pair signal wires are connected normally or reversed. This allows for error free operation in

applications where the signal wires may become inadvertently reversed during installation or maintenance. This

feature is corrected internally so no intervention from the controller or operator is required. The SN65HVD96

complies with the requirements of ANSI/TIA-4963, Electrical Characteristics of Reversible Balanced Voltage

Digital Interface Circuits.

Similar to RS-485, these transceivers can be used for point-to-point, multi-drop, or multi-point networks.

Sympol™ devices are not backwards compatible with, but are an upgrade to, existing RS-485 networks. The

pin-out is identical to the industry-standard SN75176 transceiver, allowing direct upgrade from RS-485 to

SymPol. Current-limited differential outputs protect in case of driver contention on a party-line bus. High receiver

input impedance allows connection of at least 32 nodes. Several fault tolerant features are integrated into the

device to protect from operational hazards. Current limiting on the driver outputs protects against short-circuit

faults, and operates independently on each driver output. An automatic thermal shutdown protects the driver

circuits against over temperature conditions. The receiver output enters a deterministic failsafe state if the bus

connection is left disconnected or if the bus wires are shorted together.

The small outline integrated circuit (SOIC) package saves board space compared to equivalent discrete

implementations. These devices are fully characterized for operation over the industrial temperature range

of –40°C to 85°C.
