DESCRIPTION
APPEARANCE
These low capacitance diode arrays with common cathode are multiple, discrete,
isolated junctions fabricated by a planar process and mounted in a 10-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 (see figure 1). This circuit
application is further complimented by the 1N6507 (separate data sheet) that has a
common anode. 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.
