hi-1828a

Manufacturer Part Number
hi-1828a
Description
Low Resistance, Single 8-channel, And Differential 4-channel, Cmos Analog Multiplexers
Manufacturer
Intersil Corporation
Datasheet
Low Resistance, Single 8-Channel, CMOS
Analog Multiplexer
The Hl-1818A is a monolithic, high performance CMOS
analog multiplexer 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. Substrate leakage
and parasitic capacitance are much lower, resulting in
extremely low static errors and high throughput rates. Low
output leakage (typically 0.1nA) and low channel ON
resistance (250:) assure optimum performance in low level
or current mode applications.
The HI-1818A is a single-ended, 8-Channel multiplexer, and is
ideally suited for medical instrumentation, telemetry systems,
and microprocessor based data acquisition systems.
