Radiation Hardened Single 8/Differential 4-Channel CMOS Analog Multiplexers

These radiation hardened monolithic CMOS multiplexers each include an array of eight analog switches, a digital decode circuit for channel selection, a voltage reference for logic thresholds, and an ENABLE input for device selection when several multiplexers are present. The Dielectric Isolation (DI) process used in fabrication of these devices eliminates the problem of latch-up. Also, DI offers much lower substrate leakage and parasitic capacitance than conventional junction-isolated CMOS. Switches are guaranteed to break-before-make, so that two channels are never shorted together. The switching threshold for each digital input is established by an internal +5V reference, providing a guaranteed minimum 2.4V for logic "1" and maximum 0.8 for logic "0". This allows direct interface without pull-up resistors to signals from most logic families: CMOS, TTL, DTL and some PMOS. For protection against transient overvoltage, the digital inputs include a series 200 resistor and a diode clamp to each supply. The is an eight channel single-ended multiplexer, and the is a four channel differential version. If input overvoltage protection is needed, the HS-0548RH and HS-0549RH multiplexers are recommended. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-95692. A "hot-link" is provided on our homepage for downloading. http://www.intersil.com/spacedefense/space.htm
