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-232RS-422 orRS-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 SP3073-3078E differential line transceivers are suitable for bidirectional communication on balanced multipoint bus transmission lines and comply with both RS485 and RS422 EIA Standards.

 

Each device consists of a differential driver and differential receiver. All devices

operate from a 3.3V power supply.  High receiver input impedance allows a large number of transceivers to share a common data bus while maintaining signal margin and without excessive loading or use of expensive repeaters.

 

The high impedance driver output is maintained over the entire common-mode voltage range from -7 to +12V. Receivers will failsafe to logic 1 output when inputs are open, shorted or terminated. Drivers include built-in short-circuit protection and a thermal-overload shutdown to protect against excessive power dissipation from bus contention or cable faults.

 

All RS485 inputs are ESD protected up to ±15kV (Air-Gap and Human Body Model) and up to ±8kV Contact discharge (IEC 1000-4-2).

 

Features:

  • ±15kV ESD protection for RS485 pins
  • 3.3V low-power operation
  • Advanced receiver-failsafe protection for open, shorted or terminated lines
  • Up to 256 Transceivers may share bus
  • Very low load for 8x greater fan-out
  • Hot Swap glitch protection RE and DE
  • Thermal shutdown protects against driver contention
  • Available in three industry standard footprints
    • SP3070E, SP3073E and SP3076E in Full-Duplex (14 pin)
    • SP3071E, SP3074E and SP3077E in Full-Duplex (8 pin)
    • SP3072E, SP3075E and SP3078E in Half-Duplex (8 pin)
  • Three applications-optimized speed grades
    • SP3070-72E: 250kbps fully slew-limited
    • SP3073-75E: 500kbps slew-limited
    • SP3076-78E: 16Mbps high speed
  • Small form factor SO-narrow packages
  • Industrial (-40 to +85oC) & Extended (-40 to +85oC) temperature grades
