HS-0508RH, HS-0509RH
Data Sheet August 1999
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 200Ω resistor and a diode clamp to each supply. The
HS-0508RH is an eight channel single-ended multiplexer,
and the HS-0509RH 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.
