The LT1715HMS#PBF is a dual, general-purpose comparator from the UltraFast™ family, specified with a maximum propagation delay of 9ns.
Supply range spans 2.7V to 12V on a single rail, or split supplies up to ±6V.
Typical CMRR is 55dB, PSRR is 80dB.
The maximum propagation delay is 9ns. That's the spec you budget for in your timing closure — from input crossing the threshold to output reaching valid logic levels.
The LT1720IMS8#PBF and LT1720IDD#PBF are also in the UltraFast™ family with 10ns delay and a slightly different package footprint.
The LT1715HMS#PBF is a dual comparator in a 10-MSOP package; the LT1714 and LT1716 are different pinouts and package options. A direct drop-in replacement requires verifying the footprint and pin compatibility against your board layout. The parametric fit (speed, supply, temperature) is close, but the mechanical swap needs a layout review.
