Comparators Procurement Notes

Verify the specific ordering suffix TE1 corresponds to the SOT-23-5 package with Sn2Bi terminal finish and reel packing format. Confirm RoHS compliance and halogen-free status as documented in the manufacturer's ordering information table. Ensure the component matches the exact part number NJU77230F-TE1 for correct pinout and electrical characteristics.

Comparators Selection Notes

Select this comparator when a single-channel solution with push-pull output is required for low-power designs. It is suitable for applications needing rail-to-rail input compatibility and high EMI immunity. Consider thermal dissipation limits based on the SOT-23-5 package and board layer configuration when designing for high ambient temperatures or significant power loads.

Comparators Part Context

This component belongs to the NJU77230/NJU77231/NJU77232 family of rail-to-rail input, push-pull output low-power CMOS comparators. The NJU77230 variant specifically provides a single channel in the SOT-23-5 or SC-88A packages.

Comparators FAQ

What is the maximum differential input voltage rating?

The absolute maximum differential input voltage is ±7V.

How does the device handle input voltages exceeding the supply rails?

Inputs are protected by ESD diodes that conduct if voltages exceed the supply by approximately 300mV. Current must be limited to 10mA or less using a restriction resistor.
