70-V Fault-Protected RS-485 Transceivers with 3.3-V to 5-V Operation

FEATURES

These devices combine a differential driver and a

differential receiver, which operate from a single

power supply. The driver differential outputs and the

receiver differential inputs are connected internally to

form a bus port suitable for half-duplex (two-wire bus)

common-mode 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

industry-standard SN75176 transceiver, making them

drop-in upgrades in most systems.

DESCRIPTION

These 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 internal current-limit

circuits allow fault survivability without causing the

high bus currents that otherwise might damage

external components or power supplies. They are

also robust to ESD events, with high levels of

protection to the JEDEC or IEC human-body-model

specification.
