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 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 ACS244 are contained in SMD 5962-98541. A "hot-link" is provided on our homepage with instructions for downloading.
