SN74HC153PW datasheet by Texas Instruments

SN74HC153PW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC153PW?
  The maximum operating frequency of the SN74HC153PW is 30 MHz.
• How do I ensure that the SN74HC153PW is properly powered?
  Ensure that the VCC pin is connected to a stable 5V power supply, and the GND pin is connected to a reliable ground. Also, decouple the power supply with a 0.1uF capacitor to reduce noise.
• What is the maximum current that the SN74HC153PW can sink or source?
  The SN74HC153PW can sink or source up to 25mA of current per output pin.
• How do I handle the enable inputs (E1 and E2) of the SN74HC153PW?
  The enable inputs (E1 and E2) are active-low, meaning that they must be pulled low to enable the device. Connect them to GND or a logic low signal to enable the device.
• What is the propagation delay of the SN74HC153PW?
  The propagation delay of the SN74HC153PW is typically around 10ns, but can vary depending on the operating frequency and load conditions.
