LTC6752HS5#TRPBF

Overview

The LTC6752HS5#TRPBF is a high-speed analog comparator featuring rail-to-rail inputs and CMOS outputs. It supports toggle rates up to 280MHz with a typical propagation delay of 2.9ns and rise/fall times of 1.2ns. The device operates on a single supply voltage ranging from 2.45V to 3.5V, drawing a quiescent current of 4.5mA. It provides an output current capability of ±22mA and includes a shutdown pin for power reduction. The component is housed in a 5-lead plastic TSOT-23 package and is specified for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input stage allows signal voltages to extend beyond both supply rails.
• CMOS outputs provide direct interfacing capabilities with standard logic devices.
• Integrated shutdown pin enables significant power reduction when the device is inactive.
• Low propagation delay dispersion ensures consistent timing performance under varying overdrive conditions.

Applications

• Clock and data recovery circuits
• High-speed line receivers
• Time of flight measurements
• Fast crystal oscillators

Procurement Notes

Verify the specific suffix HS5 corresponds to the extended temperature grade (-40°C to +125°C) and the TSOT-23-5 package configuration. Confirm that the TRPBF designation indicates tape and reel packaging suitable for automated assembly processes. Ensure compatibility with the required supply voltage levels before finalizing procurement orders.

Selection Notes

Select this comparator for applications requiring precise timing and high-frequency signal processing. The rail-to-rail input capability is critical for systems handling signals near ground or supply limits. Consider the low jitter characteristics for clock distribution networks. Evaluate the shutdown feature if power management during idle states is a system requirement.

Part Context

This component belongs to the LTC6752 family of very high-speed comparators designed for critical timing applications. The family offers various options including separate input/output supplies, adjustable hysteresis, and complementary outputs. The HS5 variant specifically denotes the high-temperature grade within the standard single-supply TSOT-23 package lineup.

Replacement Considerations

The datasheet identifies the ADCMP60X family as a direct replacement option. Verify pinout compatibility and electrical specifications against the target application requirements before substituting.
