TLV7044RTER

Comparators Overview

The TLV7044RTER is a quad-channel analog comparator from the Texas Instruments TLV704x family, housed in a 16-pin WQFN package. It operates on a supply voltage range of 1.6V to 6.5V with a quiescent current of 315nA per channel. The device features an open-drain output stage, rail-to-rail common-mode input voltage capability, and internal hysteresis. Key electrical specifications include a propagation delay of 3µs, an input offset voltage of ±8mV, and an operating temperature range from -40°C to +125°C.

Comparators Feature Summary

• Quad-channel configuration with open-drain outputs suitable for level translation
• Rail-to-rail input stage allowing operation up to 100mV beyond the supply rail
• Integrated internal hysteresis for noise immunity in harsh environments
• Power-on-reset circuitry maintains high-impedance state during power-up

Comparators Applications

• Mobile phones and tablets
• Gas detectors and smoke/heat detectors
• Motion detectors
• Servo drive position sensors

Comparators Procurement Notes

Verify the specific ordering suffix 'RTER' against the manufacturer's official orderable addendum to confirm the exact package dimensions and reel specifications. Ensure the design accounts for the exposed thermal pad connection requirements associated with the WQFN package type.

Comparators Selection Notes

Select this component when space-constrained designs require multiple comparators with low power consumption. The open-drain output allows flexible pull-up voltage selection, making it suitable for interfacing with different logic levels compared to push-pull alternatives.

Comparators Part Context

This part belongs to the TLV703x and TLV704x series of nano-power comparators designed for portable and industrial applications. The TLV704x variant specifically provides open-drain outputs, distinguishing it from the TLV703x series which utilizes push-pull outputs.

Comparators FAQ

How does the Power-On-Reset (POR) function behave for the TLV704x series?

For the TLV704x series, the POR circuit keeps the output in a high-impedance state while the supply voltage is below the minimum operating threshold.

What is the maximum input voltage range for this comparator?

The device supports a rail-to-rail common-mode input voltage range, capable of operating up to 100mV beyond the VCC power supply rail.
