Product details

Dual reset outputs save a glue gate

Both active-high and active-low reset signals are available from the same package. That means one supervisor can drive a microcontroller's active-low RESET pin and simultaneously signal an FPGA or a power-good LED with the active-high output. No external inverter needed.

Sourcing and lifecycle

The MAX814TCSA+ carries an Active lifecycle status per the manufacturer's record, and it is ROHS3 compliant. For a BOM line that needs a reliable supervisor for a 3.3V commercial-temperature design, this part is a clean fit.

Frequently asked questions

Is MAX814TCSA+ compatible with 3.3V logic?

Yes. The 3.03V threshold and push-pull outputs are directly compatible with 3.3V CMOS logic levels. The active-low output can drive a 3.3V microcontroller reset input without level shifting.

What is the difference between MAX814TCSA+ and MAX813L?

Both are single-channel supervisors with dual reset outputs, but the MAX813L typically has a different threshold voltage and reset timeout. The MAX814TCSA+ is set for a 3.03V threshold with a 140ms minimum timeout; check the MAX813L datasheet for its specific threshold and timing values. Pin compatibility should be verified per your layout.

How to test MAX814TCSA+ supervisor IC?

Apply a 3.3V supply to VCC, then ramp it below 3.03V. The reset outputs should assert (active-low goes low, active-high goes high). Raise the supply above 3.03V and measure the reset timeout duration — it should hold reset for at least 140ms before releasing. A scope on both outputs confirms the push-pull drive levels.

What is the direct replacement for MAX814TCSA+?

No direct replacement is listed in the available records. For a pin-compatible alternative, the MAX813L family is a common cross-shop candidate but verify threshold and timeout against your design requirements.
