3-INPUT VIDEO SUPER IMPOSER WITH 6dB AMPLIFIER
GENERAL DESCRIPTION
PACKAGE OUTLINE
NJM2265 is 3-input, 1-output video switch with 6dB amplifier.
Two inputs 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 luminance signal. This video switch can be
connected to TV monitor directly, as it has 6dB amplifier circuit
internally.
NJM2265 is a high performance video switch which is operated
with 5V supply voltage.
