PRODUCTION DATA
Figure 4-1 D, J, or N Package (Top View)| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| CONT | 3, 11 | Input | Controls comparator thresholds. Outputs 2/3 VDD and allows bypass capacitor connection. |
| DISCH | 1, 13 | Output | Open collector output to discharge timing capacitor. |
| GND | 7 | — | Ground. |
| OUT | 5, 9 | Output | High current timer output signal. |
| RESET | 4, 10 | Input | Active low reset input forces output and discharge low. |
| THRES | 2, 12 | Input | End of timing input. THRES > CONT sets output low and discharge low. |
| TRIG | 6, 8 | Input | Start of timing input. TRIG < 1/2 CONT sets output high and discharge open. |
| VDD | 14 | — | Power-supply voltage. |
