SN74LVC1G123DCUT

Texas Instruments · Monostable Multivibrators · VSSOP-8-0.5mm

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.
