3 Description

The THVD1454 is a flexible half-duplex RS-485

transceiver for industrial applications. The device has

features such as on-chip, 120-Ω termination resistor

and driver output slew rate control. Both the features

are pin controlled. This enables the device to be

used at any node location (end nodes or middle

nodes) in any network, slow or fast. End-equipment

designers can now design a common printed circuit

board (PCB), and configure the PCB using software

for various application needs. This can save design

and qualification time for the customers.

The bus pins are immune to high levels of IEC

Contact Discharge ESD events, eliminating the need

for additional system level protection components.

The device operates from a single 3-V to 5.5-V

supply. 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.

THVD1454 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.
