SIT3490E - Full-Duplex RS485/RS422 Transceiver

General Description

SIT3490E is a 3.0V~5.5V powered, full-duplex, low power dissipation RS-485 transceiver fully meeting the requirements of RS-485/RS-422 standard.

SIT3490E contains one driver and one receiver, both can transmit signals independently.

The SIT3490E has a 1/8-unit-load.

Key Features

  • 3.0V~5.5V supply, full-duplex.
  • 1/8 unit load, allow up to 256 transceivers on the bus.
  • Driver short-circuit output protection.
  • Strong anti-noise ability.
  • Integrated transient voltage suppression function.
  • The data transmission rate up to 14Mbps in electric noise environment.
  • ESD protection for RS-485 I/O pins ±15kV, HBM.
