Function operation:
The HOLDT function delays the transmission of the signal. When a high state is given to the IN input, the function starts a counter whose initial value is 0. When the counter reaches the value set by the user (Time) and is high at the IN input, the high state appears on the OUT output and is maintained until the appearance of high state on the reset input. The appearance of a low state on the IN input stops the counter operation and stores its value. The reappearance of the high state on the IN input starts the counter from the remembered value. When the state is high on all inputs, the counter is not working and its value is 0.
