CD74HC4067E datasheet by Texas Instruments

CD74HC4067E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4067E?
  The maximum frequency of operation for the CD74HC4067E is typically 10 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure proper power sequencing when using the CD74HC4067E?
  To ensure proper power sequencing, it is recommended to power up the VCC pin before the signal inputs, and power down the VCC pin after the signal inputs. This helps prevent latch-up and ensures reliable operation.
• What is the recommended operating voltage range for the CD74HC4067E?
  The recommended operating voltage range for the CD74HC4067E is 2V to 6V, with a typical operating voltage of 5V.
• How do I handle the enable input (EN) on the CD74HC4067E?
  The enable input (EN) is an active-low input that enables or disables the analog multiplexer. When EN is low, the multiplexer is enabled, and when EN is high, the multiplexer is disabled. It is recommended to tie EN to VCC or GND through a pull-up or pull-down resistor to ensure proper operation.
• What is the maximum current rating for the CD74HC4067E?
  The maximum current rating for the CD74HC4067E is typically 25mA per channel, but it can vary depending on the specific application and operating conditions.
