LTC488/LTC489

Quad RS485 Line Receiver

EATURE

DESCRIPTIO

■

Low Power: I_CC= 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

The LTC^®488 and LTC489 are low power differential bus/

line receivers designed for multipoint data transmission

standardRS485applicationswithextendedcommonmode

range (12V to –7V). They also meet the requirements of

RS422.
