SP3494 - +3.3V Low Power RS-485/RS-422 Transceiver

Description

The SP3494 device is a +3.3V low power half-duplex transceiver that meets the specifications of the RS-485 and RS-422 serial protocols.

This device is pin-to-pin compatible with the Exar SP3481 device as well as other popular industry standards.

Features

  • the Exar BiCMOS process, allowing low power operation without sacrificing performance. The partially slew-rate limited drivers minimize EMI and reduce reflections caused by improperly terminated cables allowing error-free data transmission. The SP3494 is a half-duplex partially slew-rate limited transceiver that will del.
