SN74AHC157RGYR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN74AHC157RGYR is 100 MHz.
  • Yes, the SN74AHC157RGYR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 3.3V supply.
  • The enable pins are active-low, meaning they need to be pulled low to enable the corresponding channel. You can connect them to GND or a logic low signal to enable the channel.
  • The propagation delay of the SN74AHC157RGYR is approximately 3.5 ns (typical) at 25°C and 3.3V supply voltage.
  • The SN74AHC157RGYR is rated for operation up to 85°C, but it's recommended to derate the device for temperatures above 70°C to ensure reliable operation.
