The recommended operating voltage range for the HEF4514BT,653 is 4.5V to 15.5V, with a typical voltage of 12V.
To ensure proper power-on and power-off, make sure to follow the recommended power-up and power-down sequences, and use a capacitor (e.g., 10nF) between VCC and GND to filter out noise and voltage spikes.
The maximum frequency of operation for the HEF4514BT,653 is 10MHz, but it's recommended to operate at a frequency below 5MHz for optimal performance and to minimize power consumption.
The output enable (OE) pin should be connected to GND to enable the outputs, and to VCC to disable the outputs. It's recommended to use a pull-down resistor (e.g., 1kΩ) to ensure the OE pin is properly biased.
The Schmitt-trigger inputs provide hysteresis, which helps to improve noise immunity and reduce the effects of slow input transitions. This allows the circuit to operate more reliably in noisy environments.
