LT1715IMS#PBF

Overview

The LT1715IMS#PBF is a dual comparator featuring independent input and output power supplies, housed in a 10-lead MSOP package. It operates within a supply voltage range of 2.7V to 12V for the input stage and 2.7V to 6V for the output stage. The device achieves a propagation delay of 4ns at 20mV overdrive and supports a maximum toggle frequency of 150MHz. Input offset voltage is specified at 4mV maximum, with an input bias current of 6µA. It functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Features separate power supplies for analog inputs and digital outputs, allowing flexible logic level translation without performance loss.
• Includes internal hysteresis to ensure stable operation with slow-moving input signals and prevent oscillation.
• Provides rail-to-rail CMOS and TTL compatible outputs that interface directly with standard logic families.
• Utilizes a pinout optimized for high-speed applications by shielding sensitive inputs from outputs using power rails.

Applications

• High speed differential line receivers
• Level translators
• Window comparators
• Crystal oscillator circuits
• Threshold detectors and discriminators

Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when ordering. Confirm the IMS designation corresponds to the industrial temperature range of -40°C to 85°C. Ensure the 10-lead MSOP footprint matches the target PCB layout requirements. Cross-reference the manufacturer's latest documentation for any updates to electrical specifications or recommended operating conditions.

Selection Notes

Select this component when independent supply voltages are required to accommodate different input signal ranges and output logic levels simultaneously. Consider the 4ns propagation delay and 150MHz toggle frequency for high-speed timing applications. Evaluate the internal hysteresis characteristics if noise immunity is critical for threshold detection. Verify that the 10-lead MSOP package size fits within the available board space constraints.

Part Context

This part belongs to the LT1715 family of UltraFast dual comparators designed for low voltage operation. It shares architectural similarities with the LT1720/LT1721 series but offers distinct independent supply capabilities. The device is manufactured by Analog Devices Inc., formerly Linear Technology Corporation, and is part of their portfolio of high-speed signal processing components.

Replacement Considerations

Public confirmed substitute part numbers include LT1715HMS#PBF for extended temperature range and LT1715IMS#TRPBF for tape and reel packaging. For single-channel applications, consider the LT1719. For quad-channel options with similar delay, review the LT1720/LT1721 series.
