TLC555CP from Texas Instruments, in a PDIP-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 | GND | power_in | Ground terminal. |
| 2 | TRIG | input | Trigger timing input; output goes high and discharge pin enters open-circuit state when trigger voltage falls below 1/2 of control voltage. |
| 3 | OUT | output | High-current timing output signal with CMOS rail-to-rail swing capability. |
| 4 | RESET | input | Active-low reset input that forces output and discharge pin to low level. |
| 5 | CONT | input | Control voltage input that sets comparator threshold levels; provides internal 2/3 VDD reference when left open and accepts bypass capacitor connection. |
| 6 | THRES | input | Threshold timing input; output and discharge pin go low when threshold voltage exceeds control voltage. |
| 7 | DISCH | tri_state | Open-collector discharge output capable of rapidly discharging external timing capacitor. |
| 8 | VDD | power_in | Positive supply voltage; operating range 2V to 15V depending on device grade. |
