Radiation Hardened Dual 4-Input AND Gate
The Radiation Hardened ACS21MS is a Dual 4-Input AND
Gate. For each gate, a HIGH level on all inputs results in a
HIGH level on the Y output. A LOW level on any input
results in a LOW level on the Y output. All inputs are
buffered and the outputs are designed for balanced
propagation delay and transition times.
The ACS21MS 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 ACS21MS are
contained in SMD 5962-98629. A “hot-link” is provided
on our homepage for downloading.
