LTC1483CS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1483CS8#PBF is an ultra-low power RS-485 transceiver manufactured by Analog Devices Inc. in an 8-pin SOIC package. It operates on a single 5V supply (4.75V to 5.25V) with a maximum data rate of 250kbps. The device features one driver and one receiver, supporting half-duplex communication. Quiescent current is typically 80µA when the driver is disabled and 500µA when enabled. In shutdown mode, current consumption drops to less than 1µA. It provides ±10kV ESD protection and supports a common-mode range from -7V to 12V.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power CMOS design significantly reduces energy consumption compared to bipolar counterparts.
• Controlled slew rate driver minimizes electromagnetic interference (EMI) radiated from RS-485 lines.
• Extended common-mode range (-7V to 12V) accommodates ground differences between devices.
• Integrated thermal shutdown circuit prevents excessive power dissipation during bus contention.

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS-422 applications
• Low power RS-485/RS-422 transceivers
• Level translator circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CS8 indicates the commercial temperature grade and SOIC-8 package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component for systems requiring low power consumption and reduced EMI emissions. Ensure the application environment stays within the 0°C to +70°C operating temperature range. Verify that the required data rate does not exceed 250kbps due to the slew-rate limited driver architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1483 series of ultra-low power RS-485 transceivers. It is pin-compatible with the LTC485. The 'C' designation specifies the commercial temperature range, while 'S8' denotes the 8-lead plastic SOIC package format.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is a pin-compatible alternative within the same product family. Other related parts include the LTC1480, LTC1481, LTC1485, and LTC1487, which offer variations in voltage support, speed, and power characteristics.
