DESCRIPTION
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 to the positive side of the power supply line and 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.
