Overview
The LT1719IS6#TRPBF is a single UltraFast comparator in a TSOT-23-6 package. It operates on a supply voltage of 2.7V to 6V with a maximum quiescent current of 9mA. The device features rail-to-rail CMOS/TTL compatible outputs and includes internal hysteresis of 7mV. Propagation delay is 4.5ns at 20mV overdrive and 13ns at 5mV overdrive. Input offset voltage is typically 2.5mV, with input bias current of 6µA. Common mode rejection ratio is 65dB and power supply rejection ratio is 80dB.
Feature Summary
- UltraFast response time optimized for low voltage operation
- Rail-to-rail output directly interfaces to TTL and CMOS logic
- Internal hysteresis ensures stable operation with slow-moving signals
- Low power shutdown mode reduces consumption to 0.1µA
Applications
- High speed differential line receiver
- Crystal oscillator circuits
- Level translators
- Threshold detectors and discriminators
- Zero-crossing detectors
Procurement Notes
Verify the IS6 suffix indicates the industrial temperature range (-40°C to 85°C) and TSOT-23-6 package. Confirm TRPBF denotes tape and reel packaging with lead-free finish. Ensure compatibility with 2.7V to 6V single supply systems requiring rail-to-rail output swing.
Selection Notes
Select this component for applications requiring fast propagation delay under low voltage conditions. The TSOT-23-6 package suits space-constrained designs. Consider the separate input/output supply capability if using the SO-8 variant, though the S6 version shares supplies. Internal hysteresis simplifies threshold detection without external components.
Part Context
Part of the LT1719 UltraFast comparator family from Analog Devices. The IS6 variant specifically provides industrial temperature rating and compact surface mount packaging. It serves as a high-speed alternative to standard comparators, offering improved slew rates and lower propagation delays for precision timing applications.
Replacement Considerations
LT1719CS6#TRPBF offers identical electrical performance but with a commercial temperature range (0°C to 70°C). For dual-channel requirements, consider the LT1720 or LT1721 series which share similar UltraFast characteristics.
