TLV7022DGKR

Comparators Overview

The TLV7022DGKR is a dual-channel micro-power comparator from Texas Instruments. It features an open-drain output stage and operates within a supply voltage range of 1.6 V to 6.5 V. The device consumes a quiescent supply current of 5 µA and provides a propagation delay of 260 ns. It supports rail-to-rail common-mode input voltage and includes internal hysteresis. The component is housed in an 8-pin VSSOP package with dimensions of 3 mm x 3 mm.

Comparators Feature Summary

• Dual-channel architecture with open-drain outputs suitable for level translation
• Rail-to-rail input capability extending beyond the positive supply rail
• Integrated internal hysteresis for noise immunity
• Fault-tolerant inputs allowing operation during power ramp sequences

Comparators Applications

• Mobile phones and tablets
• Portable and battery-powered devices
• IR receivers
• Level translators
• Threshold detectors and discriminators

Comparators Procurement Notes

Verify the specific ordering suffix DGKR corresponds to the VSSOP-8 package configuration. Confirm that the open-drain output type aligns with system pull-up requirements. Ensure the selected variant matches the required dual-channel topology and operating temperature specifications.

Comparators Selection Notes

Select this component when board space is limited and low power consumption is critical. The open-drain output requires an external pull-up resistor, making it ideal for interfacing with different logic voltage levels. Verify that the load capacitance does not exceed limits affecting rise times.

Comparators Part Context

This part belongs to the TLV701x/TLV702x family of small-size, low-power, low-voltage comparators. The TLV702x series specifically utilizes open-drain outputs, distinguishing it from the push-pull TLV701x series. Both families share similar electrical characteristics regarding speed and quiescent current.

Comparators Replacement Considerations

Direct substitutes include other parts from the TLV701x/TLV702x family such as the TLV7021 or TLV7022 variants in different packages. Cross-reference pinouts and output types carefully.
