Overview
The LT1719IS8#TRPBF is a single UltraFast comparator in an 8-lead SOIC package. It operates on a single supply from 2.7V to 6V or dual supplies up to ±5.25V. The device features rail-to-rail CMOS/TTL compatible outputs and separate input/output power supplies for flexible logic interfacing. Key electrical parameters include a propagation delay of 4.5ns at 20mV overdrive, 4.2mA quiescent current at 3V, and internal hysteresis of 7mV maximum. Input offset voltage is typically 0.4mV with a maximum of 2.5mV.
Feature Summary
- UltraFast response time optimized for low voltage operation
- Rail-to-rail output compatible with TTL and CMOS logic levels
- Separate input and output power supplies for flexible configuration
- Low power shutdown mode reducing current consumption significantly
Applications
- High speed differential line receivers
- Crystal oscillator circuits
- Level translators
- Threshold detectors and discriminators
- Zero-crossing detectors
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free finish. Confirm the IS8 designation corresponds to the industrial temperature range of -40°C to 85°C. Ensure the ordering information matches the 8-lead plastic SO package description provided in the manufacturer's documentation.
Selection Notes
Select this component when high-speed comparison is required with low voltage single-supply operation. The separate supply pins allow independent optimization of input common-mode ranges and output logic levels. Consider the internal hysteresis for noise immunity without external components. Verify that the 20mA output drive capability meets the load requirements.
Part Context
This part belongs to the LT1719 family of UltraFast comparators. It is available in both SO-8 and SOT-23 packages. The I-grade version specified here supports wider operating temperatures compared to the C-grade variant. Similar performance dual/quad versions are available in the LT1720/LT1721 series.
Replacement Considerations
Direct substitute: LT1719IS8#TRPBF.
