HS-0508RH, HS-0509RH

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

Ω 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
