LTC1384IG#PBF

Drivers, Receivers, Transceivers Overview

The LTC1384IG#PBF is a low-power RS-232 transceiver manufactured by Analog Devices Inc. It features two drivers and two receivers, operating from a single 5V supply with a typical quiescent current of 220µA in Normal mode and 35µA in Shutdown mode. The device supports data rates up to 120kbaud and utilizes four 0.1µF capacitors for its charge pump. It provides ±10kV ESD protection on I/O lines and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 20-lead SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with active receiver functionality maintained during shutdown mode
• Robust input/output protection against overvoltage and electrostatic discharge events
• Compact design requiring only four small space-saving capacitors for charge pump operation

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the G package designation corresponds to the 20-lead SSOP form factor required for your PCB layout. Ensure the IG variant matches the necessary industrial temperature rating for your deployment environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring minimal power draw while maintaining receiver availability during system sleep states. Compare against the LT1180A for pin compatibility if migrating existing designs. Consider the 20-lead SSOP footprint constraints relative to alternative packages like the SO-18 or PDIP options available within the series.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of ultra-low power RS-232 transceivers. It shares functional similarities with the LTC1382 but differs in packaging and specific feature sets such as shutdown receiver behavior. It serves as a direct replacement for legacy parts like the LT1180A in many standard serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly notes pin compatibility with the LT1180A. Designers should verify that the LT1180A's electrical characteristics meet the specific voltage swing and current requirements of the target application before substitution.
