The maximum frequency of operation for the SN74HC08D is typically around 100 MHz, but this can vary depending on the specific application and operating conditions.
To ensure proper operation, the SN74HC08D should be powered with a stable voltage supply between 2.0 V and 6.0 V, with a recommended operating voltage of 5.0 V. Additionally, decoupling capacitors should be used to filter out noise and ensure stable operation.
The input voltage threshold for the SN74HC08D is typically around 0.8 V for a logic high and 0.2 V for a logic low, but this can vary depending on the specific application and operating conditions.
Unused inputs on the SN74HC08D should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
The propagation delay for the SN74HC08D is typically around 10-20 ns, but this can vary depending on the specific application and operating conditions.
