TLC372QDG4

Comparators Overview

The TLC372QDG4 is a dual general-purpose differential comparator utilizing Texas Instruments' LinCMOS technology. It operates within a supply voltage range of 3V to 16V or ±1.5V to ±8V. The device features low supply current drain, typically 150µA at 5V. It provides push-pull outputs capable of sourcing and sinking up to 20mA. The input offset voltage is typically 5mV with an input bias current of 5pA. It functions in single or dual-supply configurations and supports output levels compatible with CMOS, MOS, open-drain, and TTL logic families.

• Window comparator designs for range verification

Comparators Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm package dimensions match the 8-SOIC footprint requirements for your PCB layout. Check for any recent obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

Comparators Selection Notes

Select this component when dual independent comparators are needed in a compact surface-mount package. Ensure the required output drive current does not exceed the 20mA limit. Verify that the input common-mode voltage range aligns with your signal sources. Consider the TLC372QDR if active production availability is critical, as the QDG4 variant may have different lifecycle status.

Comparators Part Context

This part belongs to the TLC37x family of LinCMOS comparators, designed for applications balancing speed and power efficiency. The family includes quad variants like the TLC3704 and other dual versions. These devices are engineered for general-purpose use where low cost and moderate performance are prioritized over high-speed precision applications.

Comparators Replacement Considerations

The TLC372QDR is listed as a recommended replacement by the manufacturer. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that the QDG4 may be obsolete; confirm current manufacturing status with the supplier.
