The THVD1424 is a flexible RS-485 transceiver for industrial applications. The device has features such as on-chip 120-Ω termination resistor, slew rate control and interchangeability between half and full duplex mode. All the features are pin-controlled. This enables the device to be used at any node location (end nodes or middle nodes) in any network, two-wire (half duplex) or 4-wire (full duplex), slow or fast. End-equipment designers can now design a common printed circuit board (PCB) and configure it via software for various application needs. This can save considerable 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 3 to 5.5-V bus supply, while the logic supply voltage range is 1.65 V to 5.5 V. The wide common-mode voltage range and low input leakage on bus pins makes the devices suitable for multi-point applications over long cable runs.
The device is available in a space-saving, thermally efficient 16-pin VQFN package. The device is characterized for ambient temperatures from –40°C to 125°C.
