LTC487CSW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC487CSW#TRPBF is a quad low-power RS-485 driver manufactured by Analog Devices Inc. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and features a typical supply current of 110µA. The device provides four differential outputs with an extended common mode range from -7V to +12V, supporting data rates up to 10Mb/s. It includes thermal shutdown protection and glitch-free power-up/down outputs for live insertion. Packaged in a 16-lead plastic SOIC (SW), it supports commercial temperature ranges from 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential bus drivers designed for multipoint data transmission standards
• CMOS design offering significant power savings while maintaining ruggedness against overload
• Three-state outputs maintain high impedance over the entire common mode range
• Thermal shutdown circuit prevents excessive power dissipation during faults

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 drivers
• Level translator applications
• Multipoint data transmission systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the SW package variant corresponds to the 16-lead plastic small outline form factor required for the assembly process. Ensure the commercial temperature grade meets the operational environment requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low quiescent current and extended common mode voltage tolerance. Verify compatibility with existing logic levels as inputs are TTL compatible. Consider the thermal characteristics and heat dissipation capabilities of the SOIC package if multiple drivers operate simultaneously under heavy load conditions.
