LTC1385CN#PBF

Drivers, Receivers, Transceivers Overview

The LTC1385CN#PBF is a 2-driver/2-receiver EIA/TIA-562 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3V supply and utilizes four 0.1mF capacitors for its charge pump. The device supports data rates up to 120kbaud with a 1000pF, 3kW load. Supply current is 200mA in Normal mode, 35mA in Driver Disable mode, and 0.2mA in Shutdown mode. It features –25V input overvoltage protection and –10kV ESD protection. The component is housed in an 18-lead PDIP package and operates within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown and driver disable modes
• EIA/TIA-562 compliance with high noise immunity via receiver hysteresis
• Robust I/O protection against overvoltage and electrostatic discharge

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and operating temperature range. The CN suffix indicates an 18-lead PDIP package suitable for through-hole mounting and a commercial temperature range. Confirm that the required voltage levels and interface protocols align with the system design before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing portable systems requiring RS-562 communication with minimal power consumption. Ensure the application environment remains within the 0°C to 70°C commercial temperature range. Verify that the available board space accommodates the required four external 0.1mF capacitors for the charge pump circuit.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1385 family of low-power RS-562 transceivers. It is pin-compatible with the LT1180A, facilitating direct upgrades or replacements in existing designs. The family includes variants with different packages and extended temperature ranges, such as the ISW and IN models.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1180A is documented as pin-compatible. Other family members like the LTC1385ISW#PBF offer the same functionality in a surface-mount SO package.
