TP485E

±18K ESD Protection, Bus-Polarity Correcting RS-485 Transceiver

Features

Description

The TP485E is a low-power RS-485 transceiver

with



Exceeds Requirements of EIA-485 Standard

automatic bus-polarity

correction

and

transient

Bus-Polarity Correction within 100 ms (t^FS)

Data Rate: 300 bps to 250 kbps

protection. Upon hot plug-in, the device detects and

corrects the bus polarity within the first 100 ms of bus

idling. On-chip transient protection protects the device

against IEC61000 ESD and EFT transients. This device

Works with Two Configurations:

– Failsafe Resistors Only

– Failsafe and Differential Termination Resistors

Up to 256 Nodes on a Bus (1/8 unit load)

Wide Supply Voltage 3V to 5.5V

has robust

drivers and receivers

for demanding



industrial applications. The bus pins are robust to

electrostatic discharge (ESD) events, with high levels of

protection to Human-Body Model (HBM), Air-Gap

Discharge, and Contact Discharge specifications. The

device combines a differential driver and a differential

– ±13 kV IEC61000-4-2 Contact Discharge

– +4 kV IEC61000-4-4 Fast Transient Burst

supply.

differential inputs are connected internally to form a bus

port suitable for half-duplex(two-wire bus) communication.

Applications

The device

features a wide common-mode voltage range

making the device suitable for multi-point applications

over long cable runs. The TP485E is available in both

SOIC-8 and MSOP-8 package, and is characterized from

–40°C to 125°C.
