The maximum operating frequency of the 74VHC08TTR is typically around 100 MHz, but it can vary depending on the specific application, supply voltage, and output load.
To ensure that the 74VHC08TTR operates within the recommended operating conditions, make sure to operate it within the specified temperature range (-40°C to 125°C), supply voltage range (2.0V to 5.5V), and output current range (up to 8mA per output).
The propagation delay of the 74VHC08TTR is typically around 3.5ns to 5.5ns, depending on the supply voltage and operating temperature.
Yes, the 74VHC08TTR can be used in a 3.3V system, as it is specified to operate from 2.0V to 5.5V. However, the output voltage levels may not be as high as those in a 5V system.
To ensure proper operation, it is recommended to power up the 74VHC08TTR with a slow ramp-up of the supply voltage (typically < 10ms) and to avoid sudden changes in the input signals during power-up and power-down.
