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.
