• Description: EE CMOS Zero-Power 20-Pin Universal Programmable Array Logic
• Manufacturer: Lattice Semiconductor

TYPICAL THERMAL CHARACTERISTICS
Measured at 25 C ambient. These parameters are not tested.
Plastic
The data listed for plastic
heat-flow paths in plastic-encapsulated devices are complex, making the
age surface. Tests indicate this measurement reference point is directly below the die-attach area on the bottom center of the package.
Furthermore,
perature. Therefore, the measurements can only be used in a similar environment.
