TLV3603DCKT

Comparators Overview

The TLV3603DCKT is a single-channel high-speed analog comparator from Texas Instruments, packaged in a SC-70-6 surface-mount format. It operates on a supply voltage range of 2.4 V to 5.5 V with a typical quiescent current of 7 mA. The device features rail-to-rail inputs extending 200 mV beyond the rails and push-pull CMOS outputs. Key electrical parameters include a maximum propagation delay of 3.5 ns, an input offset voltage of ±5 mV, and an input bias current of 1 µA. It supports a toggle frequency up to 325 MHz and includes dedicated pins for adjustable hysteresis control and latch functionality.

Comparators Feature Summary

• Features a dedicated LE/HYST pin that allows users to configure external resistors for adjustable hysteresis or enable a latching mode to hold the output state.
• Provides rail-to-rail input capability that extends 200 mV beyond both power supply rails, ensuring compatibility with signals exceeding standard supply limits.
• Delivers fast response times with a typical propagation delay of 2.5 ns and low overdrive dispersion, suitable for detecting narrow signal pulses.
• Outputs are push-pull CMOS type, enabling direct interfacing with digital controllers and IO expanders without requiring additional level-shifting circuitry.

Comparators Applications

• Laser distance meters
• Clock and data recovery circuits
• High speed trigger functions in oscilloscopes and logic analyzers
• Distance sensing in LIDAR systems
• Drone vision applications

Comparators Procurement Notes

Verify the specific ordering suffix 'DCKT' against the manufacturer's official datasheet to confirm the package type (SC-70-6) and tape-and-reel packaging configuration. Ensure the component meets the required ambient operating temperature range of -40°C to +125°C for your specific application environment. Cross-reference the part number with the latest revision history to account for any documentation updates or functional safety certifications.

Comparators Selection Notes

Select this component when a single-channel comparator with rail-to-rail inputs and push-pull outputs is required. The TLV3603DCKT is appropriate for designs needing adjustable hysteresis or latch capabilities via the LE/HYST pin. Consider this part for space-constrained PCB layouts due to its compact SC-70-6 footprint. It is suitable for applications demanding high toggle frequencies and narrow pulse width detection.

Comparators Part Context

The TLV3603DCKT belongs to the TLV360x family of high-speed comparators manufactured by Texas Instruments. This family includes the dual-channel TLV3602 and the basic single-channel TLV3601. While sharing similar speed characteristics, the TLV3603 variant specifically adds the LE/HYST pin for advanced noise suppression and state retention features not present in the TLV3601.

Comparators Replacement Considerations

TLV3603E provides extended temperature operation down to -55°C. TLV3601 offers identical performance but lacks the LE/HYST pin functionality. TLV3602 serves as a dual-channel alternative within the same package family.

Comparators FAQ

How is the hysteresis value determined?

The hysteresis voltage is determined by connecting an external resistor between the LE/HYST pin and ground. The datasheet specifies that a floating pin results in approximately 3 mV hysteresis, while specific resistance values like 150 kΩ or 56 kΩ yield higher hysteresis levels.

What is the function of the LE/HYST pin?

The LE/HYST pin serves a dual purpose. When connected to ground via a resistor, it enables adjustable hysteresis for noise immunity. When pulled low, it activates a latch mode that holds the output at its last active state until the pin is pulled high again.

Can the inputs exceed the supply voltage?

Yes, the input common-mode voltage range extends 200 mV beyond both the positive (VCC) and negative (VEE) supply rails, allowing the comparator to process signals slightly outside the power supply limits.
