Overview
The LTC6752HSC6-1#TRPBF is a single-channel, very high-speed comparator from the Analog Devices LTC6752 family. It features rail-to-rail inputs and CMOS outputs with a typical propagation delay of 2.9ns and toggle rates up to 280MHz. The device utilizes a separate input/output supply architecture, supporting VCC ranges from 2.45V to 5.25V and VDD from 1.71V to 3.5V. Key electrical characteristics include an input offset voltage of ±1.2mV, output current capability of ±22mA, and low jitter of 4.5ps RMS. It includes latching and adjustable hysteresis functions via the LE/HYST pin and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Rail-to-rail inputs allow operation beyond both supply rails for extended common-mode range.
- Separate input and output supplies enable direct interfacing with 1.8V logic devices.
- Integrated latching and adjustable hysteresis functionality for signal integrity.
- CMOS outputs provide robust drive capability with fast rise and fall times.
Applications
- Clock and Data Recovery circuits
- High Speed Line Receivers
- Time of Flight Measurements
- Fast Crystal Oscillators
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging containing 500 pieces. Confirm the H grade ensures performance across the full industrial temperature range of -40°C to +125°C. Ensure the SC-70-6 package matches the PCB footprint requirements. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.
Selection Notes
Select this part when separate input and output power domains are required to interface with lower voltage logic while maintaining high-speed performance. The inclusion of latching and hysteresis makes it suitable for noisy environments or applications requiring signal holding. Compare against the standard LTC6752 variants if shutdown pins or complementary outputs are not needed.
Part Context
This component belongs to the LTC6752 family of ultra-fast comparators designed for critical timing applications. The family offers various configurations including single supply, separate supply, shutdown, and latch options in packages like TSOT-23, SC70, MSOP, and QFN. It serves as a direct replacement for the ADCMP60X family in many high-speed designs.

FAQ
Does the LTC6752HSC6-1 support complementary outputs?
No, the LTC6752-1 variant provides only a single non-inverting output (Q). Complementary outputs are available on the LTC6752-3 variant.
What is the function of the LE/HYST pin?
The LE/HYST pin controls the latching mode and adjusts the input hysteresis voltage. Pulling it low enables latching, while varying its voltage changes the hysteresis level.
