Additional Details

The UPD4066BG is typically packaged in a DIP or SOIC package. Each switch is controlled by an individual control input. A HIGH logic level on the control input closes the switch (ON), while a LOW logic level opens the switch (OFF). Its operating temperature range is usually between 0°C to +70°C. Detailed electrical specifications, including ON-resistance values, OFF-resistance values, and switching times, are available in the NEC datasheet. This part number is often utilized in older designs requiring a reliable analog switching solution.
