PRODUCTION DATA
The THVD1400V is a half duplex RS-485 transceiver. The device has slew rate control pin SLR which can be used to set the device in maximum 20 Mbps mode or slew rate limited 500 kbps mode. THVD1400V also has low level logic interface VIO pin to run RS-485 bus at 3 to 5.5 V supply, while the microcontroller can be at any voltage between 1.65 V to 5.5 V. This feature eliminates any level shifter that may be otherwise needed between the microcontroller and the RS-485 transceiver.
