TLC555DTR from XBLW, 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 | GND | power_in | Ground; supply return, 0 V reference. |
| 2 | TRIG | input | Trigger input; TRIG < 1/2 CONT sets output high and discharge open; trigger current ≤50 nA typical. |
| 3 | OUT | output | High-current timer output signal; output current absolute maximum 100 mA. |
| 4 | RESET | input | Active-low reset input; forces output low and discharge switch on; reset voltage threshold 0.4-1.2 V. |
| 5 | CONT | input | Control voltage input; sets comparator thresholds to 2/3 VCC internally; accepts external override voltage or bypass capacitor. |
| 6 | THRES | input | Threshold (end-of-timing) input; THRES > CONT sets output low and discharge low; threshold current ≤50 nA typical. |
| 7 | DISCH | tri_state | Open-collector discharge output; discharges external timing capacitor when the output is low; discharge saturation voltage ≤100-400 mV at 10 mA. |
| 8 | VCC | power_in | Power-supply voltage; operating range 4.5 V to 15 V, absolute maximum 18 V; supply current 40-150 µA typical. |
