ACS253MS
Radiation Hardened
Dual 4-Input Multiplexer with Three-State Outputs
November 1997
Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
• 1.25Micron Radiation Hardened SOS CMOS
The Radiation Hardened ACS253MS is a Dual 4-Channel Mul-
tiplexer having two common binary control inputs for selecting 1
of 4 data channels. All inputs and outputs are buffered and are
designed for balanced propagation delay and transition times.
• Radiation Environment
- Latch-up Free Under any Conditions
Separate Output Enable inputs are provided to ease system
design. When OE1 or OE2 are set HIGH, the corresponding
output is configured into a high impedance state.

The ACS253MS 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.
