Overview
The Analog Devices LTC6752HSC6-4#TRPBF is a high-speed analog comparator featuring rail-to-rail inputs and CMOS outputs. It supports toggle rates up to 280MHz with a propagation delay of 2.9ns and rise/fall times of 1.2ns. The device utilizes separate input (VCC) and output (VDD) supplies, allowing VCC operation from 2.45V to 5.25V and VDD down to 1.71V for direct interfacing with 1.8V logic. It includes latching and adjustable hysteresis capabilities via the LE/HYST pin, operates within a temperature range of -40°C to 125°C, and is housed in a 6-lead SC-70 package.
Feature Summary
- Features separate input and output supply rails to support diverse voltage levels and direct interfacing with low-voltage logic devices.
- Includes a latch function and adjustable hysteresis controlled by an external pin for signal conditioning and noise immunity.
- Provides complementary outputs for differential signaling applications.
Applications
- Clock and data recovery circuits
- High-speed line receivers
- Time of flight measurements
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging containing 500 pieces. Confirm the H grade ensures performance across the extended industrial temperature range of -40°C to 125°C. Ensure the SC-70 package dimensions match the PCB footprint requirements. Cross-reference the part number against the manufacturer's current product status to confirm availability.
Selection Notes
Select this component when separate input and output supply voltages are required to interface with different logic families. The inclusion of latching and adjustable hysteresis makes it suitable for noisy environments or applications requiring signal holding. Verify that the 280MHz toggle rate meets the system timing requirements and that the SC-70 package fits the design constraints.
Part Context
This part belongs to the LTC6752 family of ultra-high-speed comparators. The family offers various configurations including single supply, shutdown options, and different packages like TSOT-23, MSOP, and QFN. The LTC6752-4 variant specifically provides complementary outputs and latching/hysteresis features in a compact SC-70 form factor.
Replacement Considerations
The datasheet identifies the ADCMP60X family as a direct replacement option. Verify electrical compatibility and pinout alignment before substitution.
