Overview
The LT1715HMS#TRPBF is an UltraFast dual comparator featuring independent input and output power supplies, optimized for low voltage operation. It offers a propagation delay of 4ns at 20mV overdrive and a maximum toggle frequency of 150MHz. The device operates with supply voltages ranging from 2.7V to 12V for the input stage and 2.7V to 6V for the output stage. It includes internal hysteresis and rail-to-rail outputs compatible with TTL and CMOS logic levels.
Feature Summary
- Independent input and output power supplies allow separate analog input ranges and output logic levels without performance loss.
- UltraFast switching speed with 4ns propagation delay at 20mV overdrive and 150MHz maximum toggle frequency.
- Internal hysteresis ensures stable operation with slow-moving input signals and prevents oscillations.
- Rail-to-rail outputs directly interface with 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 suffix TRPBF indicates tape and reel packaging when ordering. Confirm the H grade specifies the -40°C to 125°C operating temperature range. Ensure the MSOP package type matches your PCB footprint requirements. Cross-reference the manufacturer's latest documentation for any updates to electrical characteristics or pin configurations before finalizing procurement.
Selection Notes
Select this component when independent supply rails are required to isolate input common-mode ranges from output logic levels. Choose the H variant for industrial temperature applications up to 125°C. Consider the 150MHz toggle frequency for high-speed signal processing. Verify that the 4ns propagation delay meets system timing constraints. Ensure the 10-pin MSOP package fits the available board space.
Part Context
The LT1715 series includes variants like the LT1715C and LT1715I with different temperature specifications. The LT1719 is a single comparator version, while the LT1720/LT1721 offer quad configurations. This part belongs to Linear Technology's UltraFast comparator family, designed for high-speed precision applications requiring minimal propagation delay and jitter.

FAQ
How does the independent supply configuration benefit circuit design?
It allows the input stage and output stage to operate at different voltage levels, enabling flexible interface options with various logic families without compromising input sensitivity or output drive capability.
What is the purpose of the internal hysteresis in the LT1715?
Internal hysteresis prevents output oscillation caused by noise or slow-moving input signals, ensuring clean transitions and stable operation without requiring external feedback components.
