Features

  • 1/8 Unit-load option available (up to 256 nodes on the bus)
  • Bus-pin ESD protection exceeds 15kV HBM
  • Optional driver output transition times for signaling rates(1) of 1Mbps, 5Mbps, and 25Mbps
  • Low-current standby mode: <1µA
  • Glitch-free power-up and power-down protection for hot-plugging applications
  • 5V Tolerant inputs
  • Bus idle, open, and short-circuit fail safe
  • Driver current limiting and thermal shutdown

Description

The SN65HVD3x-EP devices are 3-state differential line drivers and differential-input line receivers that operate with 3V 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 ISO 8482:1993 standard-compliant devices.

The SN65HVD30 is fully enabled with no external enabling pins.

The SN65HVD33 has active-high driver enables and active-low receiver enables. A low (less than 1µA) standby current is achieved by disabling both the driver and receiver.

All devices are characterized for operation from –55°C to 125°C.
