SN74LS374NSR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS374NSR is 35 MHz.
  • To ensure that the outputs are in a high-impedance state during power-up, connect the OE (output enable) pin to VCC or use an external pull-up resistor to VCC.
  • The SN74LS374NSR can sink up to 24 mA and source up to -15 mA per output.
  • To prevent glitches, use a synchronous design approach by synchronizing the asynchronous inputs with the clock signal using a flip-flop or a latch.
  • The recommended operating voltage range for the SN74LS374NSR is 4.75 V to 5.25 V.
