Additional Details

The UPD4066BC is typically available in a DIP (Dual In-line Package). The control inputs determine the state of each switch. When the control input is HIGH, the switch is closed (ON), allowing signal transmission. When the control input is LOW, the switch is open (OFF), isolating the signal. It operates over a standard temperature range, typically 0°C to +70°C. Detailed electrical characteristics, such as ON-resistance, OFF-resistance, and switching speeds, can be found in the device's datasheet provided by NEC. This part is commonly used in legacy equipment and provides a reliable switching solution.
