SN54LS90J Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN54LS90J is 25 MHz.
  • No, the SN54LS90J is a 5V device and is not compatible with 3.3V systems.
  • The SN54LS90J has a Master Reset (MR) input that can be used to reset the counter. A low signal on the MR input resets the counter to zero.
  • Yes, the SN54LS90J can be used as a frequency divider. The device can divide the input clock frequency by 2, 4, 8, or 10, depending on the mode of operation.
  • The typical power consumption of the SN54LS90J is 135 mW, but this can vary depending on the operating frequency and load conditions.
