The maximum operating frequency of the 74HCT4052D,118 is 30 MHz, but it can vary depending on the specific application and operating conditions.
Yes, the 74HCT4052D,118 is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage range.
When not in use, the enable inputs (E1 and E2) should be tied to a logic level (either VCC or GND) to prevent unwanted switching and reduce power consumption.
The maximum current that can be sourced or sunk by the 74HCT4052D,118 is 20mA per output pin, but it's recommended to limit the current to 10mA or less to ensure reliable operation.
The 74HCT4052D,118 is rated for operation up to 125°C, but it's recommended to derate the device for high-temperature applications to ensure reliable operation and prevent thermal damage.
