LTC1382IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC1382IN#PBF is a 5V low power RS-232 transceiver with shutdown functionality, manufactured by Analog Devices Inc. It operates from a single 5V supply and features two drivers and two receivers. The quiescent supply current is 220µA in Normal mode and drops to 0.2µA in Shutdown mode. The device utilizes four 0.1µF capacitors for its charge pump and supports data rates up to 120kBaud. Driver outputs can withstand ±25V without damage, and the component offers ESD protection exceeding ±10kV. It is housed in an 18-lead PDIP package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown mode reducing supply current to 0.2µA
• Robust I/O lines capable of withstanding ±25V overvoltage without damage
• High ESD protection rating exceeding ±10kV on driver outputs and receiver inputs
• Space-efficient design requiring only four small 0.1µF capacitors for charge pumping

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix IN#PBF corresponds to the 18-lead PDIP package and the commercial temperature range (0°C to 70°C). Confirm that the RoHS compliance status matches current manufacturing standards. Ensure the component source is authorized to guarantee authenticity and traceability for critical system integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single 5V supply is available and ultra-low power consumption is required during idle periods. The shutdown pin allows complete control over the charge pump and driver states. Verify that the 120kBaud maximum data rate meets the communication requirements of the target application interface.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1382 family of 5V RS-232 transceivers. It is pin-compatible with the LT1180A, facilitating direct upgrades or replacements in existing designs. Related parts include variants like the LTC1383 and LTC1384, which offer similar power characteristics but differ in package size or shutdown behavior.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the LTC1382 is pin compatible with the LT1180A. Designers should verify electrical parameter alignment before substituting.
