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.
