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.
