Description
The Radiation Hardened ACS151MS is an 8-Channel Multi-
plexer having three binary control inputs and an active low
enable input. The three binary input signals select the input
from 1 of 8 channels.
Complementary data outputs are provided for ease of system
design. If the enable input is high, the input signals are disre-
garded, the Y output is set high and the Y output is set low. All
inputs and outputs are buffered and are designed for balanced
propagation delay and transition times.
The ACS151MS 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.
Specifications 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 Specifications for the ACS151 are
contained in SMD 5962-97640. A "hot-link" is provided
on our homepage with instructions for downloading.
