LT1719IS6#TRM

Overview

The LT1719IS6#TRM is a single UltraFast comparator in a TSOT-23-6 package. It operates on a single supply voltage ranging from 2.7V to 6V. The device features rail-to-rail CMOS/TTL compatible outputs and includes internal hysteresis for noise immunity. A dedicated shutdown pin enables low power consumption with quiescent current as low as 0.1µA. Propagation delay is specified at 4.5ns with 20mV overdrive and 7ns with 5mV overdrive.

Feature Summary

• UltraFast propagation delay optimized for high-speed signal processing
• Rail-to-rail output stage compatible with TTL and CMOS logic levels
• Integrated internal hysteresis eliminates need for external components
• Low power shutdown mode extends battery life in portable applications

Applications

• High speed differential line receivers
• Crystal oscillator circuits
• Threshold detectors and discriminators
• Zero-crossing detectors
• Level translators

Procurement Notes

Verify the specific suffix TRM indicates tape and reel packaging distinct from TRPBF. Confirm the IS6 designation matches the required industrial temperature range and TSOT-23-6 footprint. Ensure the datasheet revision aligns with design requirements before finalizing procurement orders.

Selection Notes

Select this component when ultrafast response times are critical alongside low voltage operation. The TSOT-23-6 package suits space-constrained designs requiring single-supply functionality. Consider the SO-8 variant if separate input and output power supplies are necessary for flexible logic level interfacing.

Part Context

This part belongs to the LT1719 family of UltraFast comparators designed for low voltage applications. It shares performance characteristics with dual and quad variants like the LT1720 and LT1721. The IS6 grade ensures operation across the full industrial temperature range within the compact six-lead thin SOT package.

Replacement Considerations

LT1719IS6#TRPBF serves as the primary alternative differing only in packaging format.
