They are designed for balanced Nodes on the Bus) transmission lines and interoperation with ANSI • Bus-Pin ESD Protection Exceeds 15 kV HBM TIA/EIA-485A, TIA/EIA-422-B, ITU-T v.11 and ISO 8482:1993 standard-compliant devices. • Optional Driver Output Transition Times for Signaling Rates(1) of 1 Mbps, 5 Mbps and The SN65HVD30, SN65HVD31, SN65HVD32, 25 Mbps SN65HVD36 and SN65HVD37 are fully enabled with no external enabling pins. The SN65HVD36 and • Low-Current Standby Mode: < 1 µA SN65HVD37 implement receiver equalization • Glitch-Free Power-Up and Power-Down technology for improved performance in long Protection for Hot-Plugging Applications distance applications. • 5-V Tolerant Inputs The SN65HVD33, SN65HVD34, SN65HVD35, • Bus Idle, Open, and Short Circuit Failsafe SN65HVD38, and SN65HVD39 have active-high • Driver Current Limiting and Thermal driver enables and active-low receiver enables. A Shutdown very low, less than 1 µA, standby current can be achieved by disabling both the driver and receiver. • Meets or exceeds the requirements of ANSI The SN65HVD38 and SN65HVD39 implement TIA/EIA-485-A and RS-422 Compatible receiver equalization technology for improved • 5-V Devices available, SN65HVD50-59 performance in long distance applications. (1) The signaling rate of a line is the number of voltage All devices are characterized for operation from transitions that are made per second expressed in the units –40 °C to 85°C. bps (bits per second). The SN65HVD36 and SN65HVD38 implement receiver equalization technology for improved jitter • Utility Meters performance on differential bus applications with data rates up to 20 Mbps at cable lengths up to 160 • DTE/DCE Interfaces meters. • Industrial, Process, and Building Automation The SN65HVD37 and SN65HVD39 implement • Point-of-Sale (POS) Terminals and Networks receiver equalization technology for improved jitter performance on differential bus applications with data rates in the range of 1 to 5 Mbps at cable The SN65HVD3X devices are 3-state differential line lengths up to 1000 meters. drivers and differential-input line receivers that operate with 3.3-V power supply.
