CD74HC237E datasheet by Texas Instruments

CD74HC237E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC237E?
  The CD74HC237E can operate at frequencies up to 25 MHz.
• How do I ensure that the CD74HC237E is properly powered?
  The CD74HC237E requires a single 2-V to 6-V power supply, and it is recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper operation.
• What is the propagation delay time for the CD74HC237E?
  The propagation delay time for the CD74HC237E is typically around 10 ns to 15 ns, depending on the operating frequency and voltage.
• Can I use the CD74HC237E in a 3.3-V system?
  Yes, the CD74HC237E can operate at 3.3 V, but the input and output voltage levels may need to be adjusted accordingly.
• How do I handle the enable inputs (E1 and E2) for the CD74HC237E?
  The enable inputs (E1 and E2) are active-low, meaning that they must be pulled low to enable the device. When E1 and E2 are high, the device is disabled and the outputs are in a high-impedance state.
