LTC1386IS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1386IS#PBF is a low-power EIA/TIA562 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3V supply and features two drivers and two receivers in a 16-lead SOIC narrow package. The quiescent supply current is 200µA with unloaded outputs, rising to 350µA at maximum operating temperatures. It supports data rates up to 120kBaud with a 1000pF, 3kΩ load. The device utilizes four 0.1µF capacitors for its charge pump. Driver output voltage swings range from -4.5V to +4.5V, while receiver inputs withstand ±25V without damage. Operating temperature ranges from -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the IS variant matches the required industrial temperature range of -40°C to +85°C for your design environment. Ensure the 16-lead SOIC package dimensions align with your PCB footprint constraints before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring strict power budgeting on a single 3.3V rail. It serves as a pin-compatible alternative to the LT1181A. Verify that the 120kBaud speed meets system timing requirements. Consider the 0.1µF capacitor count if board space is limited compared to higher-capacitance alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1386 series of ultra-low power RS-232/EIA/TIA562 transceivers. It shares architectural similarities with the LTC1385 but is optimized specifically for 3.3V systems. The series focuses on minimizing power consumption in portable electronics through efficient charge pump design and low standby currents.
