HI9P0549-9

Analog Switches, Multiplexers, Demultiplexers Overview

The HI9P0549-9 is a dual-channel analog multiplexer switch IC from the HI-549 series, manufactured by Intersil. It features two independent 4:1 multiplexers housed in a single package. The device supports dual supply voltages ranging from 15 V to 15 V and operates on a 12 V single supply. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, with both turn-on and turn-off times capped at 300 ns. It is designed for industrial temperature ranges spanning from -40 C to +85 C and is available in a SOIC-Narrow-16 surface-mount package.
