DESCRIPTION
The SN65HVD3X devices are 3-state differential line drivers and differential-input line receivers that operate with 3.3-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-422-B, ITU-T V.11 and ISO8482:1993 standard-compliant devices.
The SN65HVD30, SN65HVD31, SN65HVD32, SN65HVD36 and SN65HVD37 are fully enabled with no external enabling pins. The SN65HVD36 and SN65HVD37 implement receiver equalization technology for improved performance in long distance applications.
The SN65HVD33, SN65HVD34, SN65HVD35, SN65HVD38, and SN65HVD39 have active-high driver enables and active-low receiver enables.A very low, less than luA, standby current can be achieved by disabling both the driver and receiver.The SN65HVD38 and SN65HVD39 implement receiver equalization technology for improved performance in long distance applications.
All devices are characterized for operation from 40℃ to 85℃.
The SN65HVD36 and SN65HVD38 implement receiver equalization technology for improved jitter performance on differential bus applications with data rates up to 20 Mbps at cable lengths up to 160 meters.
The SN65HVD37 and SN65HVD39 implement receiver equalization technology for improved jitter performance on differential bus applications with data rates in the range of 1 to 5 Mbps at cable lengths up to 1000 meters.
