CD74HCT112E Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD74HCT112E?
  The recommended operating voltage range for CD74HCT112E is 4.5V to 5.5V, although it can operate from 4.5V to 6V with reduced performance.
• How do I ensure signal integrity when using CD74HCT112E in high-speed applications?
  To ensure signal integrity, use a low-impedance PCB layout, keep signal traces short, and use termination resistors or capacitors as needed to minimize reflections and ringing.
• Can I use CD74HCT112E in a 3.3V system?
  While CD74HCT112E is specified for 5V operation, it can be used in 3.3V systems with some limitations. However, the output voltage levels may not meet the required specifications, and the device may not function correctly.
• How do I handle power sequencing when using CD74HCT112E in a system with multiple power supplies?
  To avoid latch-up or damage, ensure that the power supplies are sequenced such that the VCC pin is powered up before the input signals, and the input signals are stable before the VCC pin is powered down.
• What is the maximum clock frequency that CD74HCT112E can handle?
  The maximum clock frequency that CD74HCT112E can handle is typically around 30-40 MHz, although this can vary depending on the specific application and operating conditions.
