LTC1146CN

Overview

The LTC1146CN is a low-power digital isolator from Analog Devices, featuring one channel with a 3000Vrms isolation voltage rating. It operates within a supply voltage range of 4.5V to 5.5V and supports a data rate of 20kHz. The device utilizes TTL level output noise filtering to prevent glitches and allows synchronization to an external clock. It is housed in an 18-DIP package (0.300 inch width) and functions within a temperature range of 0°C to 70°C.

Feature Summary

Provides high-voltage isolation between input and output circuits
Includes internal noise filtering to eliminate output glitches
Supports synchronization with an external clock signal

Applications

Industrial process control systems requiring galvanic isolation
Medical equipment needing safe patient isolation barriers
Power electronics monitoring and gate drive applications

Procurement Notes

Verify the specific isolation rating requirement, as the series includes variants with different ratings. Confirm the package type matches the PCB footprint, specifically the 18-pin DIP configuration. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing design-in decisions.

Selection Notes

Select this component when a single-channel digital isolator with moderate speed requirements is needed. Ensure the application voltage does not exceed the specified limits. Consider the power consumption characteristics relative to other isolators in the portfolio if battery life is a critical constraint.

Part Context

This part belongs to the LTC1145/LTC1146 family of low-power digital isolators manufactured by Analog Devices. The family is designed to provide reliable signal transmission across isolation barriers while minimizing power usage. The CN suffix indicates the commercial temperature grade and PDIP packaging.

Replacement Considerations

LTC1145CN is a related variant within the same family offering a higher maximum input frequency of 200kHz compared to the 20kHz limit of the LTC1146CN.
