EL4453
Video Fader
The EL4453 is a complete fader
subsystem. It variably blends two
inputs together for such applications
as video picture-in-picture effects.
The EL4453 operates on 5V to 15V supplies and has an
analog differential input range of 2V. AC characteristics do
not change appreciably over the supply range.
The circuit has an operational temperature of -40C to +85C
and is packaged in 14-pin PDIP and SO-14.
The EL4453 is fabricated with Elantec's proprietary
complementary bipolar process which gives excellent signal
symmetry and is free from latch up.
