These low capacitance diode arrays are multiple, discrete, isolated

junctions fabricated by a planar process and mounted in a 16-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 plating

terminations or as RoHS Compliant with annealed matte-Tin finish by

adding an “e3” suffix to the part number.
