LT1714IGN

Overview

The LT1714IGN is a dual, low-power comparator from the UltraFast family. It features rail-to-rail inputs and complementary outputs compatible with TTL/CMOS logic. The device includes internal latches for data retention. It operates on single supplies from 2.4V to 12V or dual supplies from ±2.4V to ±6V. Propagation delay is typically 7ns at 20mV overdrive. Input offset voltage is specified at a maximum of 5mV. Supply current per comparator is approximately 5mA at 5V.

Feature Summary

• Rail-to-rail input common mode range extending beyond supply rails without phase reversal
• Internal TTL/CMOS compatible output latches for retaining comparison data
• Complementary rail-to-rail outputs capable of driving digital logic directly

Applications

• High speed automatic test equipment
• Current sense circuits for switching regulators
• Crystal oscillator circuits
• High speed sampling circuits
• Window comparators

Procurement Notes

Verify the specific suffix IGN indicates the industrial temperature grade (-40°C to 85°C) and the GN package type (16-lead narrow SSOP). Confirm that the datasheet specifications for the LT1714 apply to this variant. Ensure compatibility with the required supply voltage range and latch enable logic levels before integration.

Selection Notes

Select this component when dual independent comparisons are required in a compact surface-mount package. The rail-to-rail input capability simplifies biasing near supply rails. The integrated latch feature reduces external component count for signal holding applications. Verify that the 16-lead SSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the LT1713/LT1714 series of UltraFast comparators. While the LT1713 provides a single comparator in an 8-lead MSOP, the LT1714 offers two comparators in a 16-lead narrow SSOP package. Both share identical electrical characteristics regarding speed, power consumption, and input/output capabilities.
