LTC1385IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC1385IN#PBF is a low-power, dual-driver/dual-receiver EIA/TIA-562 transceiver operating from a single 3.3V supply. It features three operational modes: Normal (200µA quiescent current), Driver Disable (35mA with active receivers), and Shutdown (0.2mA). The device supports data rates up to 120kbaud and utilizes four 0.1µF capacitors for its charge pump. Receiver inputs withstand –25V overvoltage without damage, and the component provides ±10kV ESD protection. It operates within an industrial temperature range of –40°C to +85°C and is housed in an 18-lead PDIP package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with dedicated shutdown and driver disable modes
• Robust I/O lines capable of withstanding –25V overvoltage and ±10kV ESD strikes
• Minimal external component requirement using only four 0.1µF capacitors
• TTL/CMOS compatible logic inputs and outputs

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 18-lead PDIP configuration. Confirm that the required voltage levels and interface standards align with the system design specifications before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing portable systems requiring RS-562 communication with minimal power drain. It serves as a pin-compatible alternative to the LT1180A. Consider the 18-lead PDIP package for through-hole assembly requirements. Verify that the 3.3V supply rail meets the minimum operating voltage requirements for reliable charge pump operation.

Drivers, Receivers, Transceivers Part Context

The LTC1385 belongs to Analog Devices' family of ultra-low power RS-562 transceivers. It shares functional similarities with the LTC1386 but differs in package density and specific interface configurations. This part is designed specifically for battery-operated equipment where power conservation is critical during idle periods.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet identifies the LT1180A as a pin-compatible alternative. Designers should verify that the replacement part meets the specific voltage swing and current drive requirements of the target application.
