LTC1383IS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1383IS#TRPBF is a low power RS232 transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply and features two drivers and two receivers. The device supports data rates up to 120kBaud with a 2500pF, 3kΩ load. Supply current is 220µA at no load within the industrial temperature range of -40°C to 85°C. Driver outputs provide voltage swings of ±5.0V to ±7.0V. Receiver inputs tolerate ±25V without damage. The component utilizes four 0.1µF capacitors for its internal charge pump and is housed in a 16-lead plastic narrow SOIC package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the IS designation corresponds to the industrial temperature range specifications required for the intended deployment environment. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability of the Analog Devices product.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC1383IS#TRPBF for designs requiring minimal power consumption in portable systems. Ensure the application provides a stable 5V supply rail compatible with the specified operating conditions. Verify that the system logic levels align with the TTL/CMOS input thresholds defined in the electrical characteristics. Consider the 16-pin SOIC footprint constraints during PCB layout planning.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC1383 family of RS232 transceivers designed for low power applications. It serves as a pin-compatible alternative to legacy parts like the LT1181A and MAX232A. The series includes variants such as the LTC1382 and LTC1384, which offer different shutdown behaviors while maintaining similar power efficiency profiles for serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet identifies the LT1181A and MAX232A as pin-compatible alternatives. Designers should verify that substitute components meet the specific 220µA supply current requirement and ±25V receiver input tolerance if these parameters are critical to the system design.
