Product Overview
The THVD1500 is a Texas Instruments RS-485 half-duplex transceiver for Signal_Chain interface designs. It is specified for half-duplex RS-422/RS-485 operation, with a recommended supply range of 4.5 to 5.5 V and a maximum signaling rate of 500 kbps. The receiver and driver logic inputs use 2 V to VCC for high level and 0 to 0.8 V for low level.
The device is offered in an 8-pin SOIC (D) package with a 4.90 mm x 3.91 mm body size. Thermal data for the D package includes 130.1 °C/W junction-to-ambient resistance, 72.8 °C/W junction-to-case top resistance, and 73.6 °C/W junction-to-board resistance. Recommended operation covers -40 to 125 °C ambient temperature and -40 to 150 °C junction temperature.
For bus-connected applications, THVD1500 supports -7 to 12 V bus terminal input voltage, -12 to 12 V differential input voltage, and 54 Ω minimum differential load resistance. Its 1/8 unit-load bus input supports up to 256 bus nodes. Protection and immunity facts include ±16 kV HBM ESD on bus terminals and GND, ±8 kV IEC contact discharge ESD, ±10 kV IEC air-gap discharge ESD, and ±2 kV IEC 61000-4-4 electrical fast transient immunity on bus terminals.
