Overview
The LT1713IMS8#TRPBF is a single UltraFast comparator in an 8-lead MSOP package. It operates on single supplies from 2.4V to 12V or dual supplies of ±2.4V to ±6V. Key electrical parameters include a propagation delay of 7ns at 20mV overdrive, input offset voltage of 4mV max at 5V, and supply current of 5mA per comparator at 5V. The device features rail-to-rail inputs extending 100mV beyond the rails and complementary outputs capable of sinking or sourcing 10mA.
Feature Summary
- Rail-to-rail inputs extend 100mV beyond both supply rails with phase reversal protection.
- Complementary outputs interface directly to TTL or CMOS logic levels.
- Internal latch retains output data when the latch pin is held high.
- Low power consumption optimized for 3V and 5V power supplies.
Applications
- High speed automatic test equipment
- Current sense for switching regulators
- Crystal oscillator circuits
- High speed sampling circuits
Procurement Notes
Verify the specific suffix #TRPBF indicates lead-free RoHS compliance and tape-and-reel packaging. Confirm the 'I' grade designation matches the required -40°C to 85°C operating temperature range. Ensure the 8-MSOP footprint aligns with the PCB layout specifications provided in the datasheet.
Selection Notes
Select this component for applications requiring fast response times under low overdrive conditions. The rail-to-rail input capability allows operation near supply limits without performance degradation. The integrated latch feature simplifies digital interfacing by holding comparison results stable during noisy transitions.
Part Context
This part belongs to the LT1713/LT1714 family of comparators designed for ease of use in various systems. The LT1713 variant provides a single channel, whereas the LT1714 offers dual channels in a 16-lead SSOP package. Both share identical electrical characteristics and package options where available.
Replacement Considerations
LT1713IMS8#TRPBF serves as the direct replacement for the obsolete LT1713IMS8#TR.
FAQ
How does the input common mode range behave relative to the supply rails?
The common mode range extends 100mV below the negative supply and 100mV above the positive supply, independent of the actual supply voltages.
What is the function of the LATCH ENABLE pin?
Holding the latch pin high retains the current output state, effectively freezing the comparator output regardless of subsequent input changes.
