HI-1818A, HI-1828A

Data Sheet July 1999

Low Resistance, Single 8-Channel, and
Differential 4-Channel, CMOS Analog
Multiplexers

The Hl-1818A and HI-1828A are monolithic, high
performance CMOS analog multiplexers offering built-in
channel selection decoding plus an inhibit (enable) input for
disabling all channels. Dielectric Isolation (Dl) processing is
used for enhanced reliability and performance (see
Application Note 521). Substrate leakage and parasitic
capacitance are much lower, resulting in extremelylowstatic
errors and high throughput rates. Low output leakage
(typically 0.1nA) and low channel ON resistance (250Ω)
assure optimum performance in low level or current mode
applications.

The HI-1818A is a single-ended, 8-Channel multiplexer, while
the HI-1828A is a differential 4-Channel version. Either de vice
is ideally suitedformedical instrumentation,telemetry systems,
and microprocessor based data acquisition systems.

For MIL-STD-883 compliant parts, request the HI-1818A/883.
