DESCRIPTION
APPEARANCE
These low capacitance diode arrays are multiple, discrete, isolated
junctions fabricated by a planar process and mounted in a 14-PIN package
for use as steering diodes protecting up to eight 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. They are available with either Tin-Lead
plating terminations or as RoHS Compliant with annealed matte-Tin finish
by adding an “e3” suffix to the part number.
