LT1394IS8#TRPBF

Overview

The LT1394IS8#TRPBF is a single-channel UltraFast comparator in an 8-lead SOIC package. It features complementary CMOS/TTL outputs and an internal latch. Key electrical parameters include a propagation delay of 7ns typical (9ns max), input offset voltage of 0.8mV typical, and supply current of 6mA. It operates from single 5V or dual ±5V supplies with input common mode range extending to the negative rail.

Feature Summary

• UltraFast response with 7ns propagation delay for high-speed applications
• Internal TTL/CMOS compatible latch for data retention
• Complementary outputs designed for direct logic interfacing
• Input common mode range extends to the negative supply rail

Applications

• High Speed A/D Converters
• Zero-Crossing Detectors
• Current Sense for Switching Regulators
• Fast Pulse Height/Width Discriminators
• High Speed Sampling Circuits

Procurement Notes

Verify the IS8 suffix indicates industrial temperature range (-40°C to 85°C) and SOIC-8 packaging. Confirm TRPBF denotes tape and reel packaging with lead-free finish. Cross-reference datasheet revision dates to ensure parameter consistency.

Selection Notes

Select this component when low power consumption and ground-sensing inputs are required alongside fast switching speeds. The internal latch simplifies digital interface timing. Ensure supply voltages remain within the 12V total limit and input signals do not exceed absolute maximum ratings without clamping.

Part Context

Part of the LT1394 UltraFast comparator family. Pin-compatible with LT1016, LT1116, and LT1671. Manufactured by Analog Devices Inc. under the LT brand. Designed for precision applications requiring low offset voltage and high gain stability across temperature variations.

Replacement Considerations

LT1394CS8#TRPBF: Commercial temperature range variant (0°C to 70°C). LT1394IS8: Tube packaging alternative. LT1394CMS8: Commercial MSOP package variant.
