CD74HC193E datasheet by Texas Instruments

CD74HC193E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC193E can handle?
  The CD74HC193E can handle clock frequencies up to 30 MHz.
• How do I ensure that the CD74HC193E is properly reset during power-up?
  To ensure proper reset, connect the MR (Master Reset) pin to a logic high level during power-up, and then release it after the power supply has stabilized.
• What is the recommended operating voltage range for the CD74HC193E?
  The recommended operating voltage range for the CD74HC193E is 2V to 6V, with a typical operating voltage of 5V.
• Can I use the CD74HC193E in a 3.3V system?
  Yes, the CD74HC193E can be used in a 3.3V system, but the output voltage levels may not be as high as those in a 5V system.
• How do I handle the asynchronous clear (CLR) input?
  The CLR input should be synchronized with the clock signal to avoid metastability issues. It's recommended to use a flip-flop or a latch to synchronize the CLR signal with the clock.
