The maximum operating frequency of the SN74ACT374DBR is 100 MHz.
Yes, the SN74ACT374DBR is 5V tolerant, meaning it can accept input voltages up to 5.5V even when powered at 3.3V.
The propagation delay of the SN74ACT374DBR is typically around 3.5 ns at 25°C and 3.3V supply voltage.
Yes, the SN74ACT374DBR can be used in a 3.3V system with 5V inputs, but you need to ensure that the input voltage does not exceed 5.5V and that the input current does not exceed 20 mA.
The power consumption of the SN74ACT374DBR is typically around 20 μA per input at 3.3V supply voltage and 25°C.
