Overview
The LT1719CS6#TRMPBF is a single-channel UltraFast comparator in a 6-lead TSOT-23 package. It operates on a single supply voltage ranging from 2.7V to 6V with a typical quiescent current of 4.2mA at 3V and 4.6mA at 5V. The device features rail-to-rail CMOS/TTL compatible outputs capable of sourcing 4mA and sinking 10mA. Key electrical parameters include a propagation delay of 4.5ns at 20mV overdrive, an input offset voltage of 0.4mV typical, and internal hysteresis of 3.5mV typical. It supports a shutdown mode reducing current to less than 1μA.
Feature Summary
- UltraFast response with 4.5ns propagation delay at 20mV overdrive
- Rail-to-rail output optimized for direct TTL and CMOS interfacing
- Low power shutdown mode reduces quiescent current significantly
- Integrated internal hysteresis simplifies circuit design
Applications
- High speed differential line receivers
- Crystal oscillator circuits
- Threshold detectors and discriminators
- Zero-crossing detectors
- Level translators
Procurement Notes
Verify the specific suffix TRMPBF indicates tape and reel packaging when ordering. Confirm the CS6 designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the TSOT-23 footprint matches your PCB layout requirements. Check for lead-free compliance status if required by your manufacturing standards.
Selection Notes
Select this component for applications requiring fast switching speeds with low voltage operation. The single-supply architecture simplifies power distribution compared to dual-supply alternatives. Consider the internal hysteresis for noise immunity without external components. Evaluate the shutdown pin utility for battery-powered systems requiring extended standby life.
Part Context
This part belongs to the LT1719 family of UltraFast comparators manufactured by Analog Devices Inc. (formerly Linear Technology). The S6 variant specifically denotes the 6-lead ThinSOT package, distinguishing it from the SO-8 version which offers separate input and output supplies. It is designed for portable and high-speed digital applications.
Replacement Considerations
The LT1719IS6#TRMPBF serves as the industrial grade replacement offering an extended temperature range of -40°C to 85°C. For dual-channel requirements, the LT1720 or LT1721 provide similar performance characteristics within the same family.
