LT1714CGN#PBF

Overview

The LT1714CGN#PBF is a dual, low-power comparator from Analog Devices Inc. featuring rail-to-rail inputs and complementary 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. Key electrical specifications include a propagation delay of 7ns at 20mV overdrive, an input offset voltage of up to 5mV, and a supply current of 5mA per comparator at 5V. It is housed in a 16-lead narrow SSOP package.

Feature Summary

• Rail-to-rail inputs extend 100mV beyond both supply rails without phase reversal.
• Complementary outputs interface directly with TTL or CMOS logic.
• Internal latch pins retain output data when held high.
• Optimized for 3V and 5V power supply operation.

Applications

• High speed automatic test equipment
• Current sense for switching regulators
• Crystal oscillator circuits
• High speed sampling circuits
• Fast pulse height/width discriminators

Procurement Notes

Verify the specific suffix 'GN' corresponds to the 16-lead narrow SSOP package configuration. Confirm that the 'C' grade meets the required operating temperature range for your application, as it is specified from -40°C to 85°C. Ensure compatibility with the required supply voltage range and latch enable logic levels before finalizing procurement.

Selection Notes

Select this component for applications requiring dual comparators with integrated latching capabilities. It is suitable for systems needing rail-to-rail input flexibility and direct logic interfacing. Consider the 16-lead SSOP package constraints for PCB layout. Evaluate the 7ns propagation delay against system timing requirements to ensure adequate speed for signal processing tasks.

Part Context

This part belongs to the LT1713/LT1714 family of UltraFast comparators. While the LT1713 is a single-channel device in an 8-lead MSOP package, the LT1714 provides two independent channels in a 16-lead narrow SSOP package. Both share identical electrical characteristics and features, differing primarily in channel count and physical footprint.

Replacement Considerations

LT1714IGN#PBF offers the same functionality with an extended industrial temperature range guarantee compared to the CGN variant.
