15HSC Series
ADVANCE INFORMATION
DS3593-2.3
15HSC Series
RADIATION HARD HIGH SPEED CMOS/SOS LOGIC
The 15HSC Series offer the conbined benefits of low power,
high speed CMOS with the inherent latch up immunity, Single
Event Upset (SEU) immunity and high level of radiation
hardness of Silicon on Sapphire technology.
The 15HSC Series of CMOS/SOS devices are pin
compatible with the 54LS Series and the 54HSC Series, but
with a higher speed capability.
Further device types to those listed will be available shortly.
Please contact GPS for further information.

Note:
Stresses above those listed may cause permanent
damage to the device. This is a stress rating only and
functional operation of the device at these conditions, or at
any other condition above those indicated in the operations
section of this specification, is not implied. Exposure to
absolute maximum rating conditions for extended periods
may affect device reliability.
