INTERSIL ACS257MS

ACS257MS
Radiation Hardened
Quad 2-Input Multiplexer with Three-State Outputs
November 1997
Features
Description
• QML Qualified Per MIL-PRF-38535 Requirements
The Radiation Hardened ACS257MS is a Quad 2-Channel
multiplexer which selects four bits of data from one of two
sources under the control of a single select pin. The Output
Enable input is active LOW and controls all outputs. When OE
is set HIGH, all outputs are configured into a high impedance
state, regardless of all other input conditions. All inputs are buffered and the outputs are designed for balanced propagation
delay and transition times.
• 1.25Micron Radiation Hardened SOS CMOS
• Radiation Environment
- Latch-up Free Under any Conditions
- Total Dose . . . . . . . . . . . . . . . . . . . . . . 3 x 105 RAD(Si)
- SEU Immunity . . . . . . . . . . . <1 x 10-10 Errors/Bit/Day
- SEU LET Threshold . . . . . . . . . . . >100MeV/(mg/cm2)
The ACS257MS 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.
• Input Logic Levels . . .VIL = (0.3)(VCC), VIH = (0.7)(VCC)
