LTC1481IS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1481IS8#PBF is an ultralow power RS-485 transceiver manufactured by Analog Devices Inc. It supports data rates up to 2.5 Mbits/s and operates on a single 5V supply (4.75V to 5.25V). The device features one driver and one receiver in half-duplex mode, housed in an 8-lead SOIC package. Typical quiescent current is 80mA with the driver disabled and 300mA with the driver enabled. Shutdown mode reduces supply current to less than 1mA. It includes thermal shutdown protection, fail-safe receiver outputs, and ±10kV ESD protection.

Drivers, Receivers, Transceivers Feature Summary

• Ultralow power CMOS design for battery-powered applications
• Thermal shutdown circuit prevents excessive power dissipation during bus contention
• Fail-safe receiver guarantees high output state when inputs are left open
• Glitch-free driver outputs permit live insertion or removal of the transceiver

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS-422 communication systems
• Industrial level translation interfaces
• Low power serial data transmission networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications. Ensure the operating temperature range meets system requirements. Check for RoHS compliance status as indicated in the product documentation. Confirm package integrity upon receipt.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low standby current and robust fault protection. Compare performance metrics such as propagation delay and common mode range against alternative transceivers. Consider the shutdown feature for power management strategies in portable devices.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1481 series of RS-485 transceivers. It is pin-compatible with the older LTC485 model, facilitating direct upgrades for legacy designs. The IS8 suffix indicates the industrial temperature range and SOIC-8 package configuration.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is a pin-compatible predecessor. Verify that the replacement meets the specific voltage and speed requirements of the target application before substitution.
