Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
• 1.25Micron Radiation Hardened SOS CMOS
The Radiation Hardened ACS138MS is an Inverting 3-to-8
Line Decoder/Demultiplexer with three binary select inputs
(A , A and A ). If the device is enabled, these inputs deter-

The ACS138MS is fabricated on a CMOS Silicon on Sap-
phire (SOS) process, which provides an immunity to Single
Event Latch-up and the capability of highly reliable perfor-
mance in any radiation environment. These devices offer
