SN65HVD33DR Description

The SN65HVD33DR is a 3-state differential line driver and differential-input line receiver that operates with a 3.3-V power supply. This driver and receiver have separate input and output pins for full-duplex bus communication designs. It is designed for RS-422 and RS-485 data transmission over cable lengths of up to 1500 meters. The SN65HVD33DR device is fully enabled with no external enabling

pins.
