Description
General part information
THVD1406 Series
The THVD14x6 (THVD1406 and THVD1426) devices are robust half-duplex RS-485 transceivers for industrial applications. These devices feature auto-direction control using the data input pin that reduces the reliance on separate pins for driver-enable and the receiver-enable functionality. This reduces the number of isolation channels needed or number of the GPIO pins needed for logic control. The bus pins are immune to high levels of IEC ESD events eliminating need of additional system level protection components.
The devices operate from a single 3-V to 5.5-V supply. The wide common-mode voltage range and low input leakage on bus pins make devices suitable for multi-point applications over long cable runs.
The devices are available in industry standard 8-pin SOIC package for drop-in compatibility. The devices are also available in a small, space-saving SOT package. The devices are characterized for ambient temperatures from –40°C to 125°C.
