LT1715CMS#TRPBF

Overview

The LT1715CMS#TRPBF is a dual comparator from Analog Devices featuring independent input and output power supplies. 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 offers a propagation delay of 4ns at 20mV overdrive and supports a maximum toggle frequency of 150MHz. It includes internal hysteresis, rail-to-rail CMOS/TTL compatible outputs, and an input voltage range extending 100mV below the negative rail. Packaged in a 10-lead MSOP, it is specified for commercial temperature ranges.

Feature Summary

• Features separate power supplies for analog inputs and digital outputs to allow flexible logic level interfacing without performance loss.
• Includes built-in internal hysteresis to ensure stable operation with slow-moving input signals and prevent oscillation.
• Provides rail-to-rail outputs that directly interface with standard TTL and CMOS logic families.

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the CMS designation corresponds to the commercial operating temperature range requirements for your application environment. Ensure compatibility with the 10-lead MSOP footprint during PCB layout verification.

Selection Notes

Select this component when independent supply rails are required to decouple input signal ranges from output logic levels. Consider the 4ns propagation delay and 150MHz toggle capability for high-speed timing applications. Evaluate the internal hysteresis specifications if noise immunity is critical for threshold detection tasks.

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 provides distinct pinout optimizations for high-speed use. The device is manufactured by Analog Devices under the Linear Technology brand heritage.

Replacement Considerations

Public confirmed substitute part numbers: LT1715IMS#TRPBF, LT1715HMS#TRPBF.
