DESCRIPTION
APPEARANCE
These low capacitance diode arrays are multiple, discrete, isolated junctions fabricated
by a planar process and mounted in a 14-PIN ceramic DIP package for use as
steering diodes protecting up to seven I/O ports from ESD, EFT, or surge by directing
them either to the positive side of the power supply line or to ground (see Figure 1).
An external TVS diode may be added between the positive supply line and ground to
prevent overvoltage on the supply rail. They may also be used in fast switching core-
driver applications. This includes computers and peripheral equipment such as
magnetic cores, thin-film memories, plated-wire memories, etc., as well as decoding or
encoding applications. These arrays offer many advantages of integrated circuits such
as high-density packaging and improved reliability. This is a result of fewer pick and
place operations, smaller footprint, smaller weight, and elimination of various discrete
packages that may not be as user friendly in PC board mounting.
