SGM706B-SXS8G

SGMICRO · Logic Gates · SOIC-8

SGM706B-SXS8G from SGMICRO, in a SOIC-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 nMR input Active-low manual reset input with internal 234μA (VCC = +5V) pull-up current, drivable by CMOS/TTL logic or a switch to GND; if not used, leave open or connect to VCC.
2 VCC power_in Supply voltage pin; operating range 1.0V to 5.5V (absolute maximum -0.3V to 6.0V).
3 GND power_in Ground.
4 PFI input Power-fail voltage monitor input; nPFO goes low when PFI is below the 1.25V threshold, and if not used connect PFI to GND or VCC.
5 nPFO output Power-fail monitor output that goes low when PFI is lower than 1.25V and remains high when PFI is above 1.25V.
6 WDI input Watchdog input; if it stays high or low longer than the 1.6s (TYP) timeout the watchdog expires and nWDO goes low, and the watchdog is disabled if WDI is left open or connected to a three-stated buffer output.
7 nRESET output Active-low reset output delivering a 200ms (TYP) low pulse, remaining low while VCC is below the reset threshold or nMR is low, and guaranteed valid at VCC = 1V.
8 nWDO output Watchdog output that goes low when WDI stays idle for the 1.6s (TYP) timeout, has no minimum pulse width, and goes high immediately once VCC is above the reset threshold.
