ACS138MS
Radiation Hardened
3-to-8 Line Decoder/Demultiplexer
December 1997
Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
The Radiation Hardened ACS138MS is an Inverting 3-to-8
Line Decoder/Demultiplexer with three binary select inputs
(A0, A1 and A2). If the device is enabled, these inputs determine which one of the eight normally high outputs will go
low.
• 1.25Micron Radiation Hardened SOS CMOS
• Radiation Environment
- Latch-up Free Under any Conditions
- Total Dose . . . . . . . . . . . . . . . . . . . . . . 3 x 105 RAD(Si)
- SEU Immunity . . . . . . . . . . . <1 x 10-10 Errors/Bit/Day
- SEU LET Threshold . . . . . . . . . . . >100MeV/(mg/cm2)
Two active low and one active high enable inputs (E1, E2 and
E3) are provided to make cascaded decoder designs easier
to implement.
• Input Logic Levels . . . VIL = (0.3V)(VCC), VIH = (0.7V)(VCC)
The ACS138MS is fabricated on a CMOS Silicon on Sapphire (SOS) process, which provides an immunity to Single
Event Latch-up and the capability of highly reliable performance in any radiation environment. These devices offer
significant power reduction and faster performance when
compared to ALSTTL types.
• Output Current . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±12mA
• Quiescent Supply Current. . . . . . . . . . . . . . . . . . . .20µA
• Propagation Delay . . . . . . . . . . . . . . . . . . . . . . . . . . 15ns
