Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Discharge | passive | Discharge pin of timer 1 (open-collector discharge transistor): VDISL is 0.15 to 0.5 V at VCC=15 V and IDISL=15 mA, and off-state leakage is 10 nA at VCC=15 V, VDISH=15 V. |
| 2 | Threshold | input | Threshold input of timer 1: threshold voltage is 8.8 to 11.2 V at VCC=15 V, and threshold current is 250 nA max at VTH=11.2 V. |
| 3 | Control Voltage | passive | Control voltage pin of timer 1, which sets the threshold comparator reference: VCont is 8 to 11 V at VCC=15 V (10 V typical) and 2.6 to 4 V at VCC=5 V. |
| 4 | Reset | input | Active-low reset input of timer 1 (REST low forces OUT low and DISCH on): reset voltage is 0.7 to 1.5 V at VCC=15 V, and reset current is up to 1.0 mA at VRESET=0 V. |
| 5 | Output | output | Output of timer 1, which sinks up to 200 mA: VOL is 2.7 V max at IOL=200 mA and VCC=15 V, and VOH is 12.0 V min at IOH=-200 mA and VCC=15 V. |
| 6 | Trigger | input | Trigger input of timer 1: trigger voltage is 4.5 to 5.6 V at VCC=15 V (1.1 to 2.2 V at VCC=5 V), and trigger current is 500 nA max at VTRIG=0 V. |
| 7 | GND | power_in | Power ground shared by both timers. |
| 8 | Trigger | input | Trigger input of timer 2: trigger voltage is 4.5 to 5.6 V at VCC=15 V (1.1 to 2.2 V at VCC=5 V), and trigger current is 500 nA max at VTRIG=0 V. |
| 9 | Output | output | Output of timer 2, which sinks up to 200 mA: VOL is 2.7 V max at IOL=200 mA and VCC=15 V, and VOH is 12.0 V min at IOH=-200 mA and VCC=15 V. |
| 10 | Reset | input | Active-low reset input of timer 2 (REST low forces OUT low and DISCH on): reset voltage is 0.7 to 1.5 V at VCC=15 V, and reset current is up to 1.0 mA at VRESET=0 V. |
| 11 | Control Voltage | passive | Control voltage pin of timer 2, which sets the threshold comparator reference: VCont is 8 to 11 V at VCC=15 V (10 V typical) and 2.6 to 4 V at VCC=5 V. |
| 12 | Threshold | input | Threshold input of timer 2: threshold voltage is 8.8 to 11.2 V at VCC=15 V, and threshold current is 250 nA max at VTH=11.2 V. |
| 13 | Discharge | passive | Discharge pin of timer 2 (open-collector discharge transistor): VDISL is 0.15 to 0.5 V at VCC=15 V and IDISL=15 mA, and off-state leakage is 10 nA at VCC=15 V, VDISH=15 V. |
| 14 | VCC | power_in | Positive supply: operating voltage is 4.5 to 16 V, and the absolute maximum rating is 18 V. |
