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 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 over-
voltage 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.
