LTC485IS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC485IS8#TRPBF is a low power differential bus transceiver designed for multipoint data transmission in RS-485 applications. It features an extended common mode range from -7V to +12V, supporting up to ±7V ground difference between devices. The device operates on a single 5V supply with a typical supply current of 300μA. It supports data rates up to 2.5MBps with typical driver propagation delays of 30ns and skew of 5ns. The package is an 8-lead plastic SOIC (S8), and the component is specified for operation over the extended industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• CMOS design provides significant power savings while maintaining ruggedness against overload and ESD damage.
• Thermal shutdown circuit prevents excessive power dissipation by forcing driver outputs into a high impedance state during faults.
• Receiver includes a fail-safe feature that guarantees a high output state when inputs are left open.
• Power-up/down glitch-free driver outputs permit live insertion or removal of the transceiver.

Drivers, Receivers, Transceivers Applications

• Low Power RS485/RS422 Transceiver
• Level Translator

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to +85°C) and SOIC-8 package. Ensure compatibility with the required voltage levels and interface standards before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption in RS-485 networks. It is suitable where extended common mode range and thermal protection are necessary. Consider the 2.5MBps speed limit and 300μA supply current when evaluating system power budgets and performance requirements.

Drivers, Receivers, Transceivers Part Context

The LTC485 is a CMOS RS-485/RS422 transceiver offering ultralow power consumption without sacrificing ESD and latchup immunity. It was among the first CMOS devices in this category, utilizing a proprietary output stage to eliminate latchup and provide excellent ESD protection while maintaining high impedance states beyond the supply rails.

Drivers, Receivers, Transceivers Replacement Considerations

LTC1481IS8#PBF offers lower power consumption but lacks the extended common mode range. LTC2862IS8#PBF provides ±60V fault protection and pin compatibility. LTC1485CS8#PBF offers higher speed at 10Mbps but operates within a standard common mode range.
