CD74HC273M96E4 Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the CD74HC273M96E4 is 25 MHz, but it can operate up to 50 MHz with a reduced voltage supply (VCC) of 4.5V.
  • The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. If left floating, the outputs will be in a high-impedance state.
  • A simple POR circuit can be implemented using a 10kΩ resistor, a 10nF capacitor, and a diode (e.g., 1N4148) connected to the VCC pin. This ensures a clean power-up sequence and prevents latch-up.
  • Yes, the CD74HC273M96E4 can operate with a 3.3V supply voltage, but the maximum clock frequency will be reduced to around 15 MHz. Additionally, the output voltage levels may not reach the full 3.3V, so ensure your system can accommodate this.
  • To minimize power consumption in standby mode, ensure the clock input (CLK) is at a low logic level, and the output enable (OE) pin is at a high logic level. This will put the device in a low-power state.
