Product Overview

The SN65HVD33DG4 is a 3-state Differential Line Driver and Differential-Input Line Receiver that operates with 3.3V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs. They are designed for RS-422 and RS-485 data transmission over cable lengths of up to 1500 meters. It is fully enabled with no external enabling pins. The device has active-high driver enables and active-low receiver enables. A low, less than 1µA, standby current can be achieved by disabling both the driver and receiver.
  • Bus idle, open and short-circuit failsafe
  • Driver current limiting and thermal shutdown
  • Designed for RS-422 and RS-485 networks
  • Glitch-free power-up and power-down protection for hot-plugging applications
  • Line signalling rate is the number of voltage transitions made per second expressed in units of bps
  • Bus-pin ESD protection exceeds 15kV HBM
  • Green product and no Sb/Br
