AN5765
CRT heater voltage control IC
s
Overview
The AN5765 is an IC for CRT heater voltage control.
The incorporation of 4 values of heater voltage change-
over output circuit, 5 V power supply and reset circuit for
microcomputer, and the adoption of SIP 7-pin package
with fin can realize the rationalization and power saving
of the set.
