ACS244MS
March 1998
Radiation Hardened Non-Inverting,
Octal, Three-State Buffer/Line Driver
Description
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
signi鏗乧ant power reduction and faster performance when
compared to ALSTTL types.
Speci鏗乧ations for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed below must be used when ordering.
Detailed Electrical Speci鏗乧ations for the ACS244 are
contained in SMD 5962-98541. A 鈥渉ot-link鈥?is provided
