General Description

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.

They are designed for balanced transmission lines and interoperation with ANSI TIA/EIA-485A, TIA/EIA-422B, ITU-T v.11 and ISO 8482:1993 standard-compliant devices.
