• Fragile
• Non-Fragile
|
|
Mounting Method
|
Choice List
|
Indicates how the device is mounted on the printed circuit board. Choices are:
• Through Hole
• Surface Mount
|
|
Year Produced
|
Integer
|
The four-digit year in which the device was manufactured (such as 1998 or 2004).
|
|
# of Gates
|
Integer
|
The number of active gates in the package. You can determine the gate count from the logic diagram. A J-K or R-S flip flop is equivalent to 6 gates when used as part of an LSI circuit. Agate is considered to be any one of the following functions: AND, OR, exclusive OR, NAND, NOR, and inverter. When a logic diagram is not available, use a device transistor count to determine gate count using the following equations:
• For MOS, including CMOS: Gates = # of Transistors / 4
• For Bipolar, VLSI: Gates = Gates = # of Transistors / 5
• For BICMOS, Bipolar and MOS (VLSI): Gates = # of Transistors / 4
