ICM7555IBAZ-T from RENESAS, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground (0V) return for the device supply. |
| 2 | TRIGGER | input | Trigger input. A negative-going pulse below 1/3 VDD sets the internal flip-flop and drives OUTPUT high. High-impedance CMOS input. |
| 3 | OUTPUT | output | Push-pull CMOS output. Swings between GND and VDD; can source/sink limited current (typ. up to ~100 mA transient, limited by CMOS drivers). |
| 4 | RESET | input | Active-low reset. When pulled below ~0.7V, forces OUTPUT low and resets the internal flip-flop. Tie to VDD when unused. |
| 5 | CONTROL | input | Control-voltage input. Access to the internal 2/3 VDD reference node; allows external modulation of thresholds. Bypass to GND with 0.01 uF if unused. |
| 6 | THRESHOLD | input | Threshold input. When the voltage rises above 2/3 VDD, resets the internal flip-flop and drives OUTPUT low. High-impedance CMOS input. |
| 7 | DISCHARGE | output | Open-drain N-channel discharge transistor to GND, in phase with OUTPUT. Used to discharge the external timing capacitor when OUTPUT is low. |
| 8 | VDD | power_in | Positive supply, 2V to 18V. Typical supply current ~60 uA at 5V (no load). |
