The maximum frequency of operation for the SN74HC253D is 40 MHz.
Yes, the SN74HC253D is compatible with 5V systems, but it can also operate at lower voltages down to 2V.
Make sure to decouple the power supply with a 0.1uF capacitor and use a 10uF capacitor for bulk capacitance. Also, ensure that the power supply voltage is within the recommended range.
The propagation delay of the SN74HC253D is typically around 10ns, but it can vary depending on the operating conditions and load capacitance.
The SN74HC253D is rated for operation up to 125°C, but it's recommended to derate the device for reliable operation above 85°C.
