Product details

3.06V threshold supervisor in a hand-solderable TO-92

The DS1818-5+TR: Housed in a TO-92-3 through-hole package with formed leads, this part is a natural fit for breadboard prototyping, one-off repairs, or low-volume builds where hand-soldering is the norm.

Open-drain output and the pull-up resistor decision

A pull-up resistor to the logic supply rail is required — the value sets the rise time and the high-state voltage level, so it must match the downstream input threshold. This flexibility simplifies BOM consolidation in mixed-voltage systems.

Frequently asked questions

What is the reset timeout of the DS1818-5+TR?

The reset timeout is 100ms minimum. This holds the reset signal active for at least 100ms after the supply voltage rises above the 3.06V threshold, giving the system clock and core logic time to stabilize.

What package does the DS1818-5+TR come in and can I hand-solder it?

It comes in a TO-92-3 through-hole package with formed leads. The 2.54mm pin pitch and through-hole leads are straightforward to hand-solder or breadboard — no special equipment needed.
