The recommended operating voltage range for the LS4448 is 4.5V to 5.5V, although it can operate from 3.5V to 6.0V with reduced performance.
To ensure reliable operation in high-temperature environments, it is recommended to use a heat sink and ensure good thermal conductivity between the device and the heat sink. Additionally, reducing the power consumption and operating frequency can also help to reduce the junction temperature.
The maximum clock frequency that the LS4448 can support is 100 MHz, although it can operate at lower frequencies with reduced power consumption.
To implement a clock signal with a 50% duty cycle using the LS4448, you can use the internal oscillator and divide the clock frequency by 2 using the internal clock divider. Alternatively, you can use an external clock source with a 50% duty cycle.
The minimum input voltage required for the LS4448 to recognize a logic high input is typically around 2.0V, although this can vary depending on the specific application and operating conditions.
