Nexperia · Monostable Multivibrators · TSSOP-8

74LVC1G123DP-Q100H from Nexperia, 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 Negative-edge (gated active LOW-going edge) triggered input that can retrigger the monostable output pulse.
2 B input Positive-edge (active HIGH-going edge) triggered input that can retrigger the monostable output pulse; inputs accept up to 5.5 V.
3 CLR input Direct reset input: a LOW level terminates the output pulse and inhibits triggering, and the input is also positive-edge triggered.
4 GND power_in Ground (0 V); all voltages are referenced to GND.
5 Q output Active HIGH output; ±24 mA output drive at VCC = 3.0 V.
6 CEXT passive External capacitor connection for the output pulse-width timing network.
7 REXT/CEXT passive External resistor and capacitor connection; output pulse width is tW = K × REXT × CEXT, with REXT at least 1 kΩ for VCC ≥ 3.0 V (5 kΩ at 2.0 V).
8 VCC power_in Supply voltage, 1.65 V to 5.5 V recommended operating range (absolute maximum 6.5 V).
