The recommended operating voltage range for the HEF4528BT is 4.5V to 15.5V, although it can operate down to 3V with reduced performance.
To ensure proper thermal management, provide a heat sink or a thermal pad on the exposed pad of the QFN package, and maintain a maximum junction temperature of 150°C.
The maximum frequency of operation for the HEF4528BT is 100 MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
During power-up, keep the OE pin low until the power supply has reached a stable voltage. During power-down, keep the OE pin high to prevent unwanted output transitions.
The recommended input rise and fall time for the HEF4528BT is 10 ns to 100 ns to ensure proper operation and minimize power consumption.
