SN74LVC1G123DCT from lingxingic, in a TSSOP-8. 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 trigger input with Schmitt-trigger input, and the datasheet states inputs accept signals up to 5.5V. |
| 2 | B | input | Rising-edge trigger input with Schmitt-trigger input, and the datasheet states inputs accept signals up to 5.5V. |
| 3 | CLR | input | Active-low reset and rising-edge trigger input; a LOW level clears Q to low and a rising edge can also trigger the circuit. |
| 4 | GND | power_in | Ground reference at 0V. |
| 5 | Q | output | Non-inverted output that goes high for the programmed pulse width after a valid trigger. |
| 6 | CEXT | passive | External timing capacitor connection, used together with REXT/CEXT to set the output pulse width. |
| 7 | REXT/CEXT | passive | External timing resistor and capacitor connection that sets the base output pulse width together with CEXT. |
| 8 | VCC | power_in | Supply voltage, recommended range 1.65V to 5.5V; absolute maximum is -0.5V to +6.5V, and the I/O is high-impedance when VCC=0V. |
