In a CMOS integrated circuit card configuration operating upon a received data input stream and having a common power buss for the individual integrated circuits thereof, the invention comprises the connection of a power pin of all such individual integrated circuits directly to the power buss, except for the integrated circuit to which the data input stream is applied, wherein a diode of predetermined forward voltage drop is employed&mdash;having its anode connected to the power buss and its cathode connected to its associated power pin.

Power buss inhibit through data input/output lines

A secondary protection device for protecting a circuit. The device includes a first positive temperature coefficient (PTC) resistor, a bidirectional zener diode and a second PTC resistor connected in series across input terminals. Output terminals are connected across the bidirectional zener diode for providing a protected output to the circuit. A second zener diode is coupled between one end of the bidirectional zener diode and a ground potential for limiting an output voltage to the circuit.

Individual secondary protection device

An enclosure containing heat generating electrical components is provided with exterior heat fins and is enclosed within a perforated cover. The heat fins are generally planar and parallel to define vertical channels between adjacent pairs of fins. The fins are formed with a plurality of aligned notches to define a plurality of horizontal channels. The perforations in the cover are arrayed along a plurality of horizontal lines, with at least one of the horizontal lines overlying each of the horizontal channels.
