SN74LVC1G123DCUT from Texas Instruments, in a VSSOP-8-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | input | Falling-edge sensitive input; requires B and CLR to remain high for proper operation. |
| 2 | B | input | Rising-edge sensitive input; requires A to remain low and CLR to remain high for proper operation. |
| 3 | CLR | input | Active-low clear input; can also function as rising-edge sensitive input when A remains low and B remains high. |
| 4 | GND | power_in | Ground connection. |
| 5 | Q | output | Output providing the monostable pulse. |
| 6 | Cext | passive | External timing capacitor connection point. |
| 7 | Rext/Cext | passive | External timing network connection; connects to external capacitor and resistor. |
| 8 | VCC | power_in | Power supply; supports 1.65V to 5.5V supply voltage. |
