3 Description

THVD1330 is a robust half-duplex RS-485 transceiver

for industrial applications. The bus pins are immune

to high levels of IEC Contact Discharge ESD

events eliminating the need of additional system

level protection components. Both the transmitter

and receiver are capable of operating at maximum

32 Mbps signaling rate. The device is optimized

for small propagation delay variation to support timesensitive

applications such as Baseband unit (BBU)

and Remote radio unit (RRU).

The device operates from a single 3.3 V supply.

The wide common-mode voltage range and low input

leakage on bus pins make THVD1330 suitable for

multi-point applications over long cable runs.

THVD1330 is available in industry standard 8-pin

SOIC package for drop-in compatibility. The device is

characterized from –40°C to 125°C.
