SP490 - Full-Duplex RS-485 Transceivers

Description

The SP490 is a low power differential line driver/receiver meeting RS-485 and RS-422 standards up to 5Mbps.

The SP491 is identical to the SP490 with the addition of driver and receiver tri-state enable lines.

Both products feature ±200mV receiver input sensitivity, over wide common mode range.

Features

  • 5V only.
  • Low power BiCMOS.
  • Driver/receiver enable (SP491).
  • RS-485 and RS-422 drivers/receivers.
  • Pin compatible with LTC490 and SN75179 (SP490).
