TI introduces common mode, 70-V, fault-protected RS-485 transceiver family
Texas Instruments has introduced a family of +/- 70V, fault protected RS-485 transceivers that achieve overvoltage protection with no external termination needed. These low-power devices serve as drop-in upgrades to existing RS-485 designs without costly board redesigns. The new half- and full-duplex transceivers simplify design in industrial automation, motor control and heating, ventilating, and air conditioning (HVAC) equipment.
The SN65HVD17xx family is designed to survive overvoltage faults, such as direct shorts to power supplies, miswiring faults, connector failures, cable crushes, and tool misapplications. The widest common mode, from -20 V to -25 V, allows for operation in harsh environments with large ground differences. These transceivers are offered in either a SOIC or DIP package and operate at a variety of speed grades such as 128 Kbps, 1 Mbps, and 10 Mbps to meet the needs of a variety of applications.
The SN65HVD1780/1/2 operate over a wide voltage range from 3 V to 5 V, enabling applications that have fluctuating power sources. The SN65HVD1794 has a cable invert pin, which allows for simple correction bus wires that were incorrectly configured.
The ultra low-power MSP430 microcontrollers and SN65HVD17xx family can be used together to create a low-power solution for a single control node. The SN65HVD17xx family contributes to TI’s broad interface product offering, which includes families of products for
M-LVDS, LVDS, CAN, I2C, ESD, RS-485, RS-232 and PCI-Express standards.
