DEFLECTION PROCESSOR FOR MULTISYNC MONITORS
S1D2147A01
DEFLECTION PROCESSOR
The S1D2147A01is a monolithic integrated circuit assembled
in a 42 pins shrunk dual in line plastic package.
The goal of this IC is to control all the functions related to the
horizontal and vertical deflection in multimodes or multisync
monitors.
