Features & Applications
EXAR, the market leader, offers the industry's broadest line-up of UART and serial protocol transceivers solutions.

With over 200 devices, wide 2.25 to 5.5V power supply range, 1 to 128 bytes of FIFO and compliance with the universal 3.3/5V PCI, Intel and Motorola bus interfaces, including single protocol ICs that support RS-232, RS-422 or RS-485 as well as dual and multi-protocol ICs that support from 2 to 8 of the most popular interface standards with a single IC, Exar has already done the difficult work for you.

We can deliver an immediate competitive advantage to your compressed time-to-market demands accelerating initial design, to functioning prototype and finally volume production.

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.

 

The SP490 is available in 8-pin plastic DIP and 8-pin NSOIC packages for operation over the commercial and industrial temperature ranges.

 

The SP491 is available in 14-pin DIP and pin NSOIC packages for operation over the commercial and industrial temperature ranges.

 

Features:

  • +5V Only
  • Low Power BiCMOS
  • Driver/Receiver Enable (SP491)
  • RS-485 and RS-422 Drivers/Receivers
  • Pin Compatible with LTC491 and SN75180
