PRODUCTION DATA
Figure 4-1 D, P, PS, and JG Packages, 8-Pin SOIC, PDIP,
SOP, and CDIP (Top View)| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| CONT | 5 | Input | Controls comparator thresholds. Outputs 2/3 VDD and allows bypass capacitor connection. |
| DISCH | 7 | Output | Open collector output to discharge timing capacitor. |
| GND | 1 | — | Ground. |
| NC | — | — | No internal connection. |
| OUT | 3 | Output | High current timer output signal. |
| RESET | 4 | Input | Active low reset input forces output and discharge low. |
| THRES | 6 | Input | End of timing input. THRES > CONT sets output low and discharge low. |
| TRIG | 2 | Input | Start of timing input. TRIG < 1/2 CONT sets output high and discharge open. |
| VDD | 8 | — | Power-supply voltage. |
