SN74HC148DR Frequently Asked Questions (FAQ)

  • The maximum frequency of operation for the SN74HC148DR is 40 MHz.

  • Yes, the SN74HC148DR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.

  • The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.

  • The propagation delay of the SN74HC148DR is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.

  • Yes, the SN74HC148DR is compatible with 3.3V systems, but the output voltage will be limited to around 3.1V due to the internal voltage drop.
