MAX708RCSA from MSKSEMI, in a SOP-8. 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; active low, has an internal 20kΩ (10-40kΩ) pull-up and forces a reset output when pulled low. |
| 2 | VCC | power_in | Supply voltage input; the 708R reset threshold is 2.63V (2.55-2.70V) and operating supply is 3.0V to 5.5V. |
| 3 | GND | power_in | Ground reference for all signals. |
| 4 | PFI | input | Power-fail comparator input with a 1.25V threshold (1.2-1.3V) and ±25nA maximum input current. |
| 5 | !PFO | output | Power-fail comparator output, goes low when PFI falls below 1.25V. |
| 6 | NC | unconnected | No connection on the 708 series (no watchdog function). |
| 7 | !RESET | output | Active-low reset output, asserted when VCC falls below the reset threshold or !MR is low, with a 200ms typical reset pulse width. |
| 8 | RESET | output | Active-high reset output, the inverse of !RESET. |
