M74HCT573RM13TR datasheet by STMicroelectronics

M74HCT573RM13TR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for M74HCT573RM13TR?
  The recommended operating voltage range for M74HCT573RM13TR is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I handle the power-up and power-down sequences for this device?
  It's recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures proper device operation and prevents latch-up.
• What is the maximum clock frequency supported by M74HCT573RM13TR?
  The maximum clock frequency supported by M74HCT573RM13TR is 30 MHz, but it's recommended to operate at a frequency below 20 MHz for reliable operation.
• How do I ensure proper signal integrity and reduce noise in my design?
  Use proper PCB layout techniques, such as separating analog and digital signals, using ground planes, and adding decoupling capacitors to reduce noise and ensure signal integrity.
• Can I use M74HCT573RM13TR in a 3.3V system?
  While the device can operate at 3.3V, it's not recommended as it may not meet the required voltage levels for proper operation. It's recommended to use a voltage regulator or level shifter to ensure 5V operation.
