Texas Instruments 65HVD53 series Drivers Interface ICs are transceivers that are designed for RS-422 and RS-485 communication over long cable runs. They are full-duplex devices that can transmit and receive data at the same time. The SN65HVD53DR is a transceiver full 1/1 with a data rate of 25Mbps.
The SN65HVD5X devices are 3-state differential line drivers and differential-input line receivers that operate with a 5-V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs.
