SN74LS373NSR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS373NSR is 20 MHz.
  • To prevent output corruption during power-up or power-down, it is recommended to use a pull-up or pull-down resistor on the output pins, and to ensure that the clock signal is stable before applying input data.
  • No, the SN74LS373NSR is not designed to be used as a level shifter. It is a latch with a clock input, and it is not intended to translate voltage levels.
  • The maximum current that the SN74LS373NSR can sink or source is 24 mA per output pin.
  • The asynchronous clear input (CLR) should be tied to VCC or GND through a pull-up or pull-down resistor, depending on the desired clear function. It is recommended to use a Schmidt trigger buffer or a debouncer circuit to ensure clean transitions on the CLR input.
