3 Description

The SN65HVD178x devices are designed to survive

overvoltage faults such as direct shorts to power

supplies, mis-wiring faults, connector failures, cable

crushes, and tool mis-applications. The devices are

also robust to ESD events with high levels of

protection to the human-body-model specification.

The SN65HVD178x devices combine a differential

driver and a differential receiver, which operate from

a single power supply. In the SN65HVD1782, the

driver differential outputs and the receiver differential

inputs are connected internally to form a bus port

suitable for half-duplex (two-wire bus)

communication. This port features a wide commonmode

voltage range, making the devices suitable for

multipoint applications over long cable runs. These

devices are characterized from –40°C to 125°C.

These devices are pin-compatible with the industrystandard

SN75176 transceiver, making them drop-in

upgrades in most systems.

These devices are fully compliant with ANSI TIA/EIA

485-A with a 5-V supply and can operate with a 3.3-V

supply with reduced driver output voltage for lowpower

applications. For applications where operation

is required over an extended common-mode voltage

range, see the SN65HVD1785 (SLLS872) data sheet.
