MITSUMI 2-Input 1-Output Video Switch (W/75Ω driver)/3-Input 1-Output Video Switch (W/75Ω driver) MM1221~1228
2-Input 1-Output Video Switch (W/75Ω driver)/3-Input 1-Output Video Switch (W/75Ω driver)
Monolithic IC MM1221~MM1228 November 2, 2001
Outline
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.
