HEF4047BT from Nexperia, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CTC | passive | External timing capacitor (Ct) connection. Connects between CTC and RCTC to set the pulse width along with Rt. |
| 2 | RTC | passive | External timing resistor (Rt) connection. Connects between RTC and RCTC to set the pulse width along with Ct. |
| 3 | RCTC | passive | External capacitor/resistor common connection. Note: has special input protection and is more sensitive to static discharge than standard inputs. |
| 4 | ~ASTABLE | input | Complementary astable enable input (active LOW). Allows the circuit to be used as a gate-able astable multivibrator. |
| 5 | ASTABLE | input | Astable enable input (active HIGH). A HIGH level enables astable (free-running) operation. |
| 6 | -TRIGGER | input | Negative-edge trigger input for monostable mode. A trailing-edge pulse triggers the one-shot when +TRIGGER is HIGH. |
| 7 | VSS | power_in | Ground supply voltage (0 V reference). |
| 8 | +TRIGGER | input | Positive-edge trigger input for monostable mode. A leading-edge pulse triggers the one-shot when -TRIGGER is LOW. |
| 9 | MR | input | Master reset input (active HIGH). A HIGH level ensures no output pulse during power-ON conditions and can be used to terminate an output pulse at any time. |
| 10 | O | output | True buffered output (Q). Square-wave output in astable mode; one-shot pulse output in monostable mode. |
| 11 | ~O | output | Complemented buffered output (Q-bar). Inverse of the O output. |
| 12 | RETRIGGER | input | Retrigger input for monostable mode. Common pulse to RETRIGGER and +TRIGGER retriggers the multivibrator on the leading edge. |
| 13 | OSCILLATOR_OUTPUT | output | Oscillator output. In astable mode, its period is half of the O output; 50% duty factor is not guaranteed here. |
| 14 | VDD | power_in | Positive supply voltage. Operating range 3 V to 15 V (absolute max +18 V). |
