The maximum operating frequency of the 74HCT32D,652 is typically around 30-40 MHz, but this can vary depending on the specific application and operating conditions.
To ensure proper operation, the 74HCT32D,652 should be powered with a stable 5V supply, and decoupling capacitors (e.g. 100nF) should be placed close to the device to filter out noise and voltage spikes.
The 74HCT32D,652 can sink or source up to 20mA of current per output, but this should be limited to 100mA total per package to avoid overheating.
While the 74HCT32D,652 is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be fully compatible with 3.3V logic, and the device may not meet its specified propagation delay times.
Unused inputs on the 74HCT32D,652 should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper device operation.
