Overview

  • Low Power: ICC = 7mA Typ
  • Designed for RS485 or RS422 Applications
  • Single 5V Supply
  • –7V to 12V Bus Common Mode Range Permits ±7V Ground Difference Between Devices on the Bus
  • 60mV Typical Input Hysteresis
  • Receiver Maintains High Impedance in Three-State or with the Power Off
  • 28ns Typical Receiver Propagation Delay
  • Pin Compatible with the SN75173 (LTC488)
  • Pin Compatible with the SN75175 (LTC489)

The LTC488 and LTC489 are low power differential bus/line receivers designed for multipoint data transmission standard RS485 applications with extended common mode range (12V to –7V). They also meet the requirements of RS422.

The CMOS design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage.

The receiver features three-state outputs, with the receiver output maintaining high impedance over the entire common mode range.

The receiver has a fail-safe feature which guarantees a high output state when the inputs are left open.

Both AC and DC specifications are guaranteed 4.75V to 5.25V supply voltage range.
