LTC491

Differential Driver and

Receiver Pair

DESCRIPTIO

EATURE

■

Low Power: I_CC= 300µA Typical

Designed for RS485 or RS422 Applications

Single +5V Supply

–7V to +12V Bus Common Mode Range

Permits ±7V Ground Difference Between Devices

designedformultipointdatatransmissionstandardRS485

applications with extended common mode range (+12V to

–7V). It also meets the requirements of RS422.

Thermal Shutdown Protection

Power-Up/Down Glitch-Free Driver Outputs Permit

Live Insertion or Removal of Package

Driver Maintains High Impedance in Three-State or

with the Power Off

The driver and receiver feature three-state outputs, with

the driver outputs maintaining high impedance over the

entire common mode range. Excessive power dissipation

caused by bus contention or faults is prevented by a

thermal shutdown circuit which forces the driver outputs

into a high impedance state.

■

Combined Impedance of a Driver Output and

Receiver Allows up to 32 Transceivers on the Bus

70mV Typical Input Hysteresis

28ns Typical Driver Propagation Delays with 5ns

Skew

Pin Compatible with the SN75180

Both AC and DC specifications are guaranteed from 0°C to

70°C and 4.75V to 5.25V supply voltage range.
