CM1421 - ON Semiconductor

CM1421 4-Channel LCD EMI Filter Array and ESD Protection Array

The CM1421 is a multichannel array consisting of four low−pass filters with integrated ESD protection and four ESD−only protection channels designed to reduce EMI/RFI emissions on LCD data lines in mobile handsets. The CM1421 has component values of 15 pF − 100 W − 15 pF. These devices include ESD protection diodes on every pin, which provide a very high lev.
