LTC1384CN#PBF

Drivers, Receivers, Transceivers Overview

The LTC1384CN#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 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 offers ±10kV ESD protection on I/O lines and can withstand ±25V overvoltage without damage. The component is housed in an 18-lead PDIP package and operates within a temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with dedicated shutdown mode that maintains receiver functionality.
• Robust input protection allowing direct connection to RS-232 lines exposed to high voltages.
• Minimal external component requirement using standard small-value capacitors for voltage generation.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and temperature grade. Ensure the procurement channel provides genuine components with traceable manufacturing history. Cross-reference the part number with the latest datasheet revisions to confirm pinout compatibility and electrical specifications before finalizing purchase orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring minimal power dissipation from a single 5V source. It is suitable for portable applications where battery life is critical but RS-232 communication is necessary. Consider the 18-lead PDIP package constraints for through-hole assembly processes. Verify that the required data rate does not exceed 120kbaud under the specific load conditions of the application.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of ultra-low power RS-232 transceivers. It is pin-compatible with the LT1180A, facilitating design upgrades or replacements in existing circuits. The CN suffix indicates the commercial temperature range and PDIP packaging variant within the broader product line.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1180A is documented as pin-compatible. Other family members like the LTC1382 or LTC1383 offer similar electrical characteristics but may differ in package dimensions or specific feature sets such as shutdown behavior.
