The maximum frequency of operation for the HEF40106BP is typically around 10 MHz, but it can vary depending on the specific application and operating conditions.
To ensure proper power supply, connect the VDD pin to a stable voltage source between 4.5V and 15.5V, and the VSS pin to ground. Also, decouple the power supply with a 100nF capacitor.
The maximum current that the HEF40106BP can sink or source is typically around 20mA per output pin, but it's recommended to limit the current to 10mA to ensure reliable operation.
The Schmitt trigger inputs on the HEF40106BP have a built-in hysteresis, which helps to reduce noise sensitivity. However, it's still important to ensure that the input signals are clean and have a sufficient voltage swing to trigger the inputs correctly.
The HEF40106BP is rated for operation up to 125°C, but it's recommended to derate the device for high-temperature operation. Consult the datasheet for specific derating guidelines.
