Overview
The LT1714IGN#TRPBF is a dual, low-power analog comparator from Analog Devices Inc. featuring UltraFast propagation delay and rail-to-rail inputs and outputs. It operates on single supplies from 2.4V to 12V or dual supplies from ±2.4V to ±6V. The device includes internal TTL/CMOS compatible latches for data retention and handles input voltages exceeding supply rails without phase reversal. Packaged in a 16-lead narrow SSOP (GN) format, it supports industrial temperature ranges.
Feature Summary
- Rail-to-rail complementary outputs interface directly with TTL or CMOS logic
- Internal latch pins retain output data when held high
- Inputs can exceed supply rails without causing phase reversal
- Optimized for 3V and 5V power supply operation
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 TRPBF denotes tape and reel packaging. Confirm the package type matches the 16-lead narrow SSOP requirement. Ensure the order number aligns with the dual-channel configuration rather than the single-channel LT1713 variant.
Selection Notes
Select this component for applications requiring dual comparators with integrated latching capabilities. It is suitable for systems needing rail-to-rail signal handling and fast response times under low voltage conditions. Consider the 16-lead SSOP footprint constraints during PCB layout planning.
Part Context
This part belongs to the LT1713/LT1714 family of UltraFast comparators. While the LT1713 provides a single channel in an 8-lead MSOP package, the LT1714 offers two channels in a 16-lead narrow SSOP package. Both share identical electrical characteristics and latch functionality.

FAQ
How does the latch pin function?
The latch pin retains the current output state when held high. It features built-in hysteresis to protect against slow-moving or noisy latch signals.
What is the common mode input range?
The common mode range extends 100mV beyond both supply rails, allowing inputs to go slightly outside the V+ and V- limits.
