MAX708ESA+T from Analog Devices Inc Maxim Integrated, in a SOIC-8-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | MR | input | Manual-reset input triggers a reset pulse when pulled below 0.8V; it has an internal 250µA pull-up, is TTL/CMOS compatible, and is debounced by the 140ms minimum reset pulse width. |
| 2 | VCC | power_in | +5V supply input; the MAX708 operates from 4.5V to 5.5V and its reset threshold is 4.40V typical (4.25V to 4.50V). |
| 3 | GND | power_in | 0V ground reference for all signals. |
| 4 | PFI | input | Power-fail voltage monitor input; PFO goes low when PFI is below the 1.25V threshold, and it should be connected to GND or VCC when not used. |
| 5 | PFO | output | Power-fail output goes low and sinks current when PFI is less than 1.25V, otherwise it stays high. |
| 6 | N.C. | unconnected | No connection. |
| 7 | RESET | output | Active-high reset output is the inverse of RESET (active-low) and is guaranteed valid with VCC down to 1.1V. |
| 8 | RESET | output | Active-low reset output pulses low for 200ms when triggered, stays low while VCC is below the reset threshold, and remains low for 200ms after VCC rises above the threshold. |
