Radiation Hardened Single 8/Differential
4-Channel CMOS Analog Multiplexers
Features
• Electrically Screened to SMD # 5962-95692
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.
• QML Qualified per MIL-PRF-38535 Requirements

• Gamma Dose . . . . . . . . . . . . . . . . . . . . . . 1 x 10 RAD(Si)
• No Latch-Up
• No Channel Interaction During Overvoltage
• Low On Resistance . . . . . . . . . . . . . . . . . . . . <200Ω (Typ)
• 44V Maximum Power Supply
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.
