LTC1384ISW#PBF

Drivers, Receivers, Transceivers Overview

The LTC1384ISW#PBF is an ultra-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 quiescent current of 220µA in Normal mode and 35µA in Shutdown mode while keeping receivers active. 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 an 18-lead plastic SO (SW) package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown mode that maintains receiver functionality
• Integrated charge pump requiring only four small 0.1µF capacitors
• Robust input/output protection against overvoltage and electrostatic discharge

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ISW indicates the industrial temperature grade (-40°C to +85°C) and the SW package type (18-lead Plastic Small Outline). Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low standby power consumption without sacrificing receiver availability during sleep states. Ensure the application environment falls within the specified -40°C to +85°C operating range and that the 18-lead SO package footprint aligns with the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of 5V RS-232 transceivers. It is pin-compatible with the LT1180A. Related variants include the LTC1384CG (Commercial grade, SSOP package) and the LTC1384IN (Industrial grade, PDIP package), offering different packaging and temperature options within the same functional architecture.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly notes pin compatibility with the LT1180A. Designers should verify electrical parameter overlaps if substituting with other members of the LTC1384 family or cross-referencing similar industry-standard RS-232 transceivers.
