HI3-1818A

® HI-1818A Data Sheet November 19, 2004 FN3141.4 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 (250Ω) 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.
