HI1-5050-8

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-5050-8 is a high-speed CMOS analog multiplexer manufactured by Harris Corporation. It integrates an array of sixteen single-pole double-throw (SPDT) analog switches with a digital decoder circuit for channel selection. The device utilizes dielectric isolation (DI) technology to eliminate latch-up and reduce substrate leakage. It features an internal voltage reference that establishes switching thresholds, allowing direct interface with standard logic families including CMOS, TTL, DTL, and PMOS without external pull-up resistors. The component is designed for harsh environment applications and supports MIL-STD-883 qualification.
