4 Pin Configuration and Functions
Table 4-1 Pin Functions
| PIN | TYPE | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | NO. | |||
| D (SOIC),
P (PDIP), PS (SO), PW (TSSOP), JG (CDIP) |
FK (LCCC) | |||
| CONT | 5 | 12 | Input/output | Controls comparator thresholds, Outputs 2/3 × VCC, allows bypass capacitor connection |
| DISCH | 7 | 17 | Output | Open collector output to discharge timing capacitor |
| GND | 1 | 2 | — | Ground |
| NC | — | 1, 3, 4, 6, 8, 9, 11, 13, 14, 16, 18, 19 | — | No internal connection |
| OUT | 3 | 7 | Output | High current timer output signal |
| RESET | 4 | 10 | Input | Active low reset input forces output and discharge low. |
| THRES | 6 | 15 | Input | End of timing input. THRES > CONT sets output low and discharge low |
| TRIG | 2 | 5 | Input | Start of timing input. TRIG < ? CONT sets output high and discharge open |
| VCC | 8 | 20 | — | Input supply voltage, 4.5V to 16V. SE555 maximum is 18V. |
