CD74HC153M datasheet by Texas Instruments

CD74HC153M Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD74HC153M?
  The maximum operating frequency of the CD74HC153M is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure correct data propagation through the multiplexer?
  To ensure correct data propagation, make sure to meet the setup and hold times of the select inputs (S0 and S1) with respect to the clock input (CLK). Also, ensure that the data inputs (I0-I3) are stable before the rising edge of the clock.
• What is the power consumption of the CD74HC153M?
  The power consumption of the CD74HC153M depends on the operating frequency, voltage, and load conditions. However, according to the datasheet, the typical quiescent current is around 20 μA, and the dynamic current is around 1.5 mA at 1 MHz and 5 V.
• Can I use the CD74HC153M as a demultiplexer?
  Yes, the CD74HC153M can be used as a demultiplexer by connecting the output (Y) to the input of a logic circuit, and using the select inputs (S0 and S1) to control which input is routed to the output.
• What is the propagation delay of the CD74HC153M?
  The propagation delay of the CD74HC153M is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
