NJM2263
3 - INPUT VIDEO SUPER IMPOSER WITH 75Ω DRIVER
■
GENERAL DESCRIPTION
NJM2263
is 3-input, 1-output video switch with 75Ω driver circuit.
Two input are provided with sink chip clamp function, which adjust
the DC level of video signal.
The other input of transistor open base can make control of
luminalce signal.
This video switch can be connected to TV monitor directly, as it
has 75Ω driver circuit internally.
NJM2263
is a high performance
video switch with 10MHz frequency range and 70dB (at 4.43MHz)
crosstalk, which is operated with 5V supply voltage.

APPLICATION
This IC requires 1MΩ resistance between INPUT and GND pin for clamp type input since the minute current causes an
unstable pin voltage.
This IC requires 0.1uF capacitor between INPUT and GND, 1MΩ resistance between INPUT and GND for clamp type
input at mute mode.
