The maximum frequency of operation for the HEF4024BT is 10 MHz.
The HEF4024BT requires a power supply voltage (VDD) of 5V ± 10% and a ground connection (VSS) to operate properly.
The maximum input voltage that can be applied to the HEF4024BT is 5.5V.
The output of the HEF4024BT is an open-drain output, which means it can only sink current and not source current. An external pull-up resistor is required to pull the output high.
The propagation delay of the HEF4024BT is typically 10 ns.
