Radiation Hardened
TTL Input, 3-to-8 Line Decoder/Demultiplexer
Description
The Radiation Hardened ACTS138MS is an Inverting 3-to-8
Line Decoder/Demultiplexer with three TTL level binary
select inputs (A
0
, A
1
and A
2
). If the device is enabled, these
inputs determine which one of the eight normally high out-
puts will go low.
Two active low and one active high enable inputs (E
1
, E
2
and
E
3
) are provided to make cascaded decoder designs easier
to implement.
The ACTS138MS 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 ACTS138 are
contained in SMD 5962-98535. A 鈥渉ot-link鈥?is provided
