Product details

Dual comparator for general-purpose threshold and zero-crossing detection

It operates from a single 2.7V to 16V supply or dual ±1.35V to ±8V rails.

Supply voltage range and input characteristics

Input bias current is 1 pA typical at 5V, which suits high-impedance sources like photodiodes or pH probes where leakage would shift the threshold. Maximum input offset voltage is 5 mV at 10V supply, adequate for general-purpose level detection but not precision instrumentation.

Low quiescent current and push-pull output

Quiescent current is 25 µA max per comparator. The push-pull output can sink or source 20 mA typical.

The 8-SOIC package is widely stocked and easy to reflow in standard SMT lines.

Frequently asked questions

Is TS3702CDT RoHS compliant?

Yes, the TS3702CDT is ROHS3 compliant.

Is TS3702CDT a drop-in replacement for LM393?

Not directly. The TS3702CDT has CMOS push-pull outputs, while the LM393 has open-collector outputs. The TS3702CDT does not require an external pull-up resistor for a high output, but the pinout is the same (8-DIP/SOIC). Verify the output stage matches your circuit before substituting.
