Additional Details

The 74V221AMTC operates over a wide supply voltage range, making it compatible with various logic families. The output pulse width is determined by the values of the external resistor (Rext) and capacitor (Cext) connected to the timing pins. The Schmitt-trigger inputs ensure reliable triggering even with slow or noisy input signals. The retriggerable capability allows the output pulse to be extended by applying another trigger pulse before the initial pulse has completed. The low power consumption makes it suitable for battery-powered applications. The TSSOP package provides a compact footprint for space-constrained designs. ON Semiconductor's commitment to quality ensures that the 74V221AMTC delivers reliable performance in a wide range of applications.
