HS-0506RH,
HS-0507RH
Radiation Hardened Single 16/Differential
8 Channel CMOS Analog Multiplexer
September 1997
Features
Description
• Low On Resistance 400Ω Max
• Wide Analog Signal Range ±15V
• TTL/CMOS Compatible 2.4V (Logic “1”)
• Access Time 1000ns Max
These radiation hardened monolithic CMOS multiplexers
each include an array of sixteen analog switches, a digital
decode circuit for channel selection, 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 latchup. Also, DI
offers much lower substate leakage and parasitic
capacitance than conventional junction isolated CMOS. 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 0.8V for logic “0”. This allows
direct interface without pullup 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 diode clamp to each
supply. The HS-0506RH is a sixteen channel single-ended
multiplexer, and the HS-0507RH is an eight channel
differential version. If input overvoltage protection is needed,
the HS-0506RH or HS-0507RH multiplexers are
recommended. For further information see Application Notes
520 and 521.
