3 Description
The THVD1400V is a half-duplex RS-422/RS-485
transceiver for industrial applications. The device has
features such as 3 to 5.5 V bus supply, 1.65 V to
5.5 V low level logic interface support. This device has
slew rate select feature that enables it to be used at
two maximum speeds based on the SLR pin setting.
Separate logic supply pin eliminates the need for an
additional level shifter when the MCU and RS-485
transceivers are operating with different supplies.
The bus pins are immune to high levels of IEC
Contact Discharge ESD events eliminating the need
for additional system level protection components.
The wide common-mode voltage range and low input
leakage on bus pins makes the device suitable for
multi-point applications over long cable runs.
THVD1400V is available in space-saving thermally
efficient 10-VSON package (3 mm x 3 mm). The
device is characterized for ambient temperature from
–40°C to 125°C.
