Single 8-Channel CMOS Analog Multiplexer
HI-508/883 Features The HI-508/883 is an eight channel single-ended multiplexer.
This monolithic CMOS multiplexer includes 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. This Circuit is Processed in Accordance to MIL-STD-883 and
is Fully Conformant Under the Provisions of Paragraph 1.2.1. The Dielectric Isolation (DI) process used in fabrication of this
device 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 0.8V 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. If input overvoltage protection is needed, the
HI-548/883 and HI-549/883 multiplexers are recommended.
