Overview
The LT1714IGN#PBF is a dual, low-power comparator from the UltraFast series. It features rail-to-rail inputs and complementary outputs compatible with TTL or 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 specified at 7ns with 20mV overdrive. Input offset voltage is typically 3mV at 5V supply. Supply current per comparator is approximately 5mA.
Feature Summary
- Rail-to-rail input common mode range extends beyond both supply rails without phase reversal.
- Complementary outputs interface directly to digital logic families.
- Internal latch pins retain output states when asserted high.
- Optimized for operation at 3V, 5V, and -5V power supplies.
Applications
- High speed automatic test equipment
- Current sense circuits for switching regulators
- Crystal oscillator circuits
- High speed sampling circuits
Procurement Notes
Verify the specific suffix IGN#PBF against the manufacturer's latest documentation to confirm package type and temperature grade. Ensure the ordering information matches the required 16-lead narrow SSOP configuration. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring dual comparators with integrated latching functionality. The rail-to-rail input capability allows signal processing near supply limits. Verify that the 16-lead package fits the available board space. Consider the propagation delay specifications relative to the system timing requirements.
Part Context
This part belongs to the LT1713/LT1714 family of UltraFast comparators manufactured by Analog Devices Inc. The LT1714 variant specifically provides two independent channels within a single package. The family is characterized by high speed performance and low power consumption suitable for portable and industrial systems.
