NJW1342
47µF AC-Coupling Capacitor
4in-2out Video Driver with Isolation Amplifier
QGENERAL DESCRIPTION
NJW1342 is 47uF AC-Coupling Capacitor 4in-2out Video Driver with
Isolation Amplifier. It can remove common mode noise because internal
Isolation amplifier. It can reduce (47uF) usual output capacitor
by NJRC original “ASC(Advanced SAG Correction)”, and contributes to
space saving.
NJW1342 is the best for the switch of the video signal of car AV.
