Overview
The MC12080DG is a single modulus prescaler designed by onsemi for low power frequency division of high frequency input signals up to 1.1 GHz. This component is particularly useful for applications requiring precise frequency division by factors of 10, 20, 40, or 80. The divide ratio is controlled by inputs SW1, SW2, and SW3, allowing for flexible configuration based on the application's requirements. The MC12080DG operates within a supply voltage range of 4.5 to 5.5 V and is known for its low power consumption, typically 3.7 mA at 5.0 V. It is also RoHS compliant and available in Pb-free packages, ensuring environmental sustainability and reliability.
