Description
The Harris CA1391E and CA1394E are monolithic
integrated circuits designed for use in the low-level
horizontal section of monochrome or color television
receivers. Functions include a phase detector, an oscillator,
a regulator, and a pre-driver.
The CA1391E and CA1394E are electrically equivalent and
pin compatible with industry types 1391 and 1394 in similar
packages.
