ACS244MS
Radiation Hardened Non-Inverting,
Octal, Three-State Buffer/Line Driver
March 1998
Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
• 1.25Micron Radiation Hardened SOS CMOS
The Radiation Hardened ACS244MS is a Non-Inverting,
Octal, Three-State Buffer/Line Driver with two active-LOW
Enable inputs (AE and BE). Each Enable input controls four
outputs. When an Enable input is LOW, the corresponding
outputs are active. A HIGH on an Enable input causes the
corresponding outputs to be high impedance, regardless of
the input levels.

The ACS244MS 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
significant power reduction and faster performance when
compared to ALSTTL types.
