LT1719CS6#TRPBF

Overview

The LT1719CS6#TRPBF is a single UltraFast comparator in a 6-lead TSOT-23 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. Key electrical specifications include a propagation delay of 4.5ns at 20mV overdrive, a quiescent supply current of 4.2mA at 3V, and a shutdown mode consuming less than 1μA. The input common-mode range extends from V– – 0.1V to V+ – 1.2V.

Feature Summary

• UltraFast response with 4.5ns propagation delay at 20mV overdrive
• Rail-to-rail output optimized for direct interface with TTL and CMOS logic
• Low power shutdown mode reduces current consumption to under 1μA
• Internal hysteresis simplifies usage with slow-moving input signals

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 when sourcing. Confirm the CS6 designation corresponds to the commercial temperature grade (0°C to 70°C) rather than the IS8 industrial variant. Ensure the 6-lead TSOT-23 package matches the PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component for applications requiring fast switching speeds within a low-voltage single-supply environment. The TSOT-23 package is suitable for space-constrained designs. Consider the SO-8 variant if separate input and output power supplies are required for flexible logic level translation. Evaluate the internal hysteresis against external requirements to determine if additional feedback resistors are necessary for specific noise margins.

Part Context

This part belongs to the LT1719 family of UltraFast comparators manufactured by Analog Devices Inc. (formerly Linear Technology). The family includes dual and quad variants such as the LT1720 and LT1721. The CS6 specifically denotes the single-channel version in a compact surface-mount package designed for portable and high-density electronic systems.
