LTC1482CMS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1482CMS8#PBF is a low power RS-485 transceiver in an 8-lead MSOP package. It operates on a single 5V supply with a maximum data rate of 4Mbps. Supply current is 700µA max with the driver disabled and 900µA max when enabled. Shutdown mode draws 20µA max. The device features an active low open-drain carrier detect output, receiver fail-safe for floating inputs, and enhanced ESD protection rated at –15kV (HBM). It supports up to 32 transceivers on the bus and includes thermal shutdown protection.

Drivers, Receivers, Transceivers Feature Summary

• Active low carrier detect output allows detection of cable insertion or removal and enables multiple transceivers to share a common line.
• Receiver fail-safe guarantees a high output state when inputs are floating, shorted, or terminated without a signal present.
• Enhanced ESD protection withstands –15kV human body model and IEC-1000-4-2 levels without latchup or damage.
• Thermal shutdown circuit forces driver outputs to high impedance during excessive power dissipation from bus contention.

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS422 communication systems
• Low power industrial RS-485 networks
• Level translation between logic domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free and RoHS compliance status according to Analog Devices documentation. Confirm the MSOP package marking matches the ordered part number. Ensure the commercial temperature range (0°C to +70°C) aligns with the target application environment requirements before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring integrated carrier detection to simplify bus management. The low quiescent current makes it suitable for battery-operated devices. Verify that the 4Mbps data rate meets system speed requirements. Consider the 8-lead MSOP package constraints for PCB layout and thermal dissipation in dense designs.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1482 family of low power RS-485 transceivers. It is available in MSOP, PDIP, and SO packages. The CMS8 variant specifically denotes the commercial temperature grade and MSOP plastic small outline package. Other variants include the industrial grade LTC1482IS8.

Drivers, Receivers, Transceivers Replacement Considerations

LTC1482CS8#PBF is a pin-compatible alternative in an SOIC-8 package. LTC1482IN8 offers the same functionality in a PDIP package. Verify package dimensions and thermal characteristics when substituting these variants.
