Monolithic IC MM1221~MM1228

Outline

November 2, 2001

These ICs are high-end video switch ICs with 2-input 1-output or 3-input 1-output including a 75Ω driver. The

series includes those with and without a built-in clamp circuit and a 6dB amp.

The circuit configuration table and block diagram are shown below.

MM1228 is introduced as a representative model in this document.
