MAX4574EEI

Analog Switches - Special Purpose Overview

The MAX4574EEI+ is a serially controlled, clickless audio and video switch IC manufactured by Analog Devices Inc. (Maxim Integrated). It features a configuration of two SPST and six SPDT switches housed in a 28-pin QSOP package. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V, with a typical operating voltage of 5 V. Key electrical parameters include a maximum on-resistance of 35 Ohms, a bandwidth of 150 MHz, and a maximum turn-on time of 8 ns. The typical off-isolation is specified at -90 dB for SPDT and -50 dB for SPST channels. The component supports a power dissipation of 860 mW and functions within an operating temperature range of 0°C to +70°C.
