TLV7021DCKT

Comparators Overview

The TLV7021DCKT is a single-channel analog comparator from Texas Instruments, housed in a SC-70-5 surface-mount package. It operates within a supply voltage range of 1.6 V to 5.5 V and supports dual supplies up to ±2.75 V. The device features an open-drain output and delivers a typical propagation delay of 350 ns at 5 V. Key electrical parameters include a maximum input offset voltage of 8 mV, a typical input bias current of 5 pA, and a quiescent current of 10 µA. It maintains a common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) of 78 dB, functioning reliably across an industrial temperature range of -40°C to +125°C.

Comparators Feature Summary

• Features rail-to-rail input capability for wide signal compatibility
• Provides low-power operation with minimal quiescent current consumption
• Delivers high-speed response with nanosecond-scale propagation delay
• Includes internal hysteresis to improve noise immunity

Comparators Applications

• Portable battery-powered equipment requiring low standby current
• Threshold detection circuits in consumer electronics
• Voltage monitoring systems for microcontrollers
• Signal conditioning interfaces for sensors

Comparators Procurement Notes

Verify the specific suffix 'DCKT' corresponds to the SC-70-5 package and tape-and-reel quantity configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design alignment with the specified operating temperature range and supply voltage limits to maintain performance specifications.

Comparators Selection Notes

Select this component when a single comparator with ultra-low input bias current is required. The SC-70-5 package offers space efficiency for compact designs. Consider the 350 ns propagation delay for timing-sensitive applications. Verify that the open-drain output architecture matches the system logic levels and pull-up requirements.

Comparators Part Context

This part belongs to the TLV7021 series of general-purpose comparators. It shares functional similarities with other members like the TLV7021DBVR but differs in packaging. The series targets portable applications where power conservation and small form factors are critical constraints.

Comparators Replacement Considerations

Check datasheets for pin-compatible alternatives such as the TLV7021DBVR or TLV7021DPWR. Verify that substitute parts match the 1.6 V minimum supply voltage and 350 ns propagation delay specifications.
