The recommended operating voltage range for the CD74HCT40103E is 4.5V to 5.5V, with a typical operating voltage of 5V.
Unused inputs on the CD74HCT40103E should be tied to VCC or GND to prevent floating inputs, which can cause unwanted oscillations or power consumption.
The maximum clock frequency that the CD74HCT40103E can handle is 25 MHz, but this can vary depending on the specific application and operating conditions.
While the CD74HCT40103E 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 compatible with 3.3V logic, and the device may not meet the specified timing parameters.
To ensure proper power-up and initialization, the CD74HCT40103E should be powered up with a monotonic voltage ramp, and the clock input should be stable before applying any input signals.
