Description

The SN65HVD5X devices are 3-state differential linedrivers and differential-input line receivers thatoperate with a 5-V power supply. Each driver andreceiver has separate input and output pins forfull-duplex bus communication designs. SN65HVD5X is designed for balanced transmission lines andinteroperation with ANSI TIA/EIA-485A,TIA/EIA-422-B, ITU-T v.11 and ISO 8482:1993tandard-compliant devices.
