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 25 The SN65HVD30, SN65HVD31, SN65HVD32, 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 distance Protection for Hot-Plugging Applications applications. • 5V Tolerant Inputs The SN65HVD33, SN65HVD34, SN65HVD35, • Bus Idle, Open, and Short Circuit Failsafe SN65HVD38, and SN65HVD39 have active-high • Meets or exceeds the requirements of ANSI driver enables and active-low receiver enables. A TIA/EIA-485-A and RS-422 Compatible very low, less than 1 µA, standby current can be achieved by disabling both the driver and receiver. • 5-V Devices available, SN65HVD50-59 The SN65HVD38 and SN65HVD39 implement receiver equalization technology for improved performance in long distance applications. • Utility Meters All devices are characterized for operation from -40 °C • DTE/DCE Interfaces to +85 °C. • Industrial, Process, and Building Automation The SN65HVD36 and SN65HVD38 implement • Point-of-Sale (POS) Terminals and Networks receiver equalization technology for improved jitter performance on differential bus applications with data rates up to 20 Mbps at cable lengths up to 160 The SN65HVD3X devices are 3-state differential line meters. drivers and differential-input line receivers that The SN65HVD37 and SN65HVD39 implement operate with 3.3-V power supply. receiver equalization technology for improved jitter performance on differential bus applications with data (1) The signaling rate of a line is the number of voltage rates in the range of 1 to 5 Mbps at cable lengths up transitions that are made per second expressed in the units bps (bits per second). to 1000 meters. IMPROVED REPLACEMENT FOR: Part Number Replace with xxx3491 SN65HVD33: Better ESD protection (15kV vs 2kV or not specified) Higher Signaling Rate (25Mbps vs 20Mbps) Fractional Unit Load (64 Nodes vs 32) MAX3491E SN65HVD33: Higher Signaling Rate (25Mbps vs 12Mbps) Fractional Unit Load (64 Nodes vs 32) MAX3076E SN65HVD33: Higher Signaling Rate (25Mbps vs 16Mbps) Lower Standby Current (1 µA vs 10 µA) MAX3073E SN65HVD34: Higher Signaling Rate (5Mbps vs 500kbps) Lower Standby Current (1 µA vs 10 µA) MAX3070E SN65HVD35: Higher Signaling Rate (1Mbps vs 250kbps) Lower Standby Current (1 µA vs 10 µA) Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
