Product details

4.65 V threshold — the 5 V rail supervisor this part is

Its 4.65 V threshold means it holds the reset output active-low until the supply rises above that level, then releases after a 140 ms minimum timeout. This gives the processor or logic a clean start with the supply fully settled. The output is push-pull, so no external pull-up resistor is needed on the reset line.

This removes any LTB pressure for new BOMs or ongoing production. The part is ROHS3 compliant.

Through-hole 8-PDIP — board-level fit

Housed in an 8-pin PDIP (0.300" width, 7.62 mm pitch), this is a through-hole package for socketed or hand-assembled boards. The supplier device package is 8-PDIP.

Frequently asked questions

Can MAX709LCPA+ be used with 3.3 V microcontrollers?

No, the 4.65 V threshold is designed for 5 V rails. For 3.3 V systems, a supervisor with a lower threshold (e.g., 3.08 V or 2.93 V) would be needed.

Is MAX709LCPA+ a direct replacement for MAX709LCUA+?

The MAX709LCUA+ is the same die in a different package (8-µMAX vs 8-PDIP). The electrical specs — threshold, timeout, output type — are identical, but the footprint differs. They are not pin-compatible without a board change.
