Radiation Hardened Inverting 3-to-8 Line
Decoder/Demultiplexer
Intersil‘s Satellite Applications
(SAF) devices are
fully tested and guaranteed to 100kRAD total dose. These
QML Class T devices are processed to a standard flow
intended to meet the cost and shorter lead-time needs of
large volume satellite manufacturers, while maintaining a
high level of reliability.
The Intersil HCS138T is a Radiation Hardened 3-to-8 Line
Decoder/Demultiplexer. The outputs are active in the low
state. Two active low and one active high enables (E1, E2,
E3) are provided. If the device is enabled, the binary inputs
(A0, A1, A2) determine which one of the eight normally high
outputs will go to a low logic level.
