DG408CY Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DG408CY?
  The recommended power-up sequence is to apply VDD first, followed by VSS, and then the logic inputs. This ensures proper device operation and prevents latch-up.
• How do I ensure that the DG408CY switches correctly between the two analog signal paths?
  To ensure correct switching, the digital control inputs (S0-S3) should be driven with a low-impedance source, and the analog signal paths should be properly terminated to prevent signal reflections.
• What is the maximum allowable voltage on the analog signal pins?
  The maximum allowable voltage on the analog signal pins is VDD + 0.3V or VSS - 0.3V, whichever is less. Exceeding this voltage may cause damage to the device.
• Can I use the DG408CY as a multiplexer or demultiplexer?
  Yes, the DG408CY can be used as either a multiplexer or demultiplexer, depending on the application. The device can be configured to connect one of eight analog inputs to a common output (multiplexer) or to connect a common input to one of eight analog outputs (demultiplexer).
• How do I minimize power consumption when the device is not in use?
  To minimize power consumption when the device is not in use, the VDD supply should be turned off, and the digital control inputs (S0-S3) should be driven low to place the device in a low-power standby mode.
