LTC1384CSW#PBF

Drivers, Receivers, Transceivers Overview

The LTC1384CSW#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 provides ±10kV ESD protection on I/O lines and withstands ±25V overvoltage without damage. The component is housed in an 18-lead SOIC (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 electrostatic discharge and overvoltage conditions

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the SW package designation matches the required 18-lead plastic small outline footprint for PCB layout compatibility. Ensure the CSW suffix corresponds to the commercial temperature range specifications defined in the official datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring minimal power consumption during standby periods. The ability to keep receivers active during driver shutdown is critical for remote wake-up applications. Verify that the 120kbaud maximum data rate meets the system communication requirements and that the 5V supply voltage aligns with the target logic levels.

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 series, facilitating direct upgrades or replacements in existing designs. The family includes variants with different packages and temperature ranges, such as the CG and ISW versions, offering flexibility for various form factors and environmental conditions.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1180A is explicitly noted as pin-compatible in the documentation. Other family members like the LTC1382 or LTC1383 offer similar electrical characteristics but may differ in package type or pin count.
