DG9424DQ-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9424DQ-T1 is a low voltage, dual supply, low on-resistance quad single-pole-single-throw analog switch manufactured by Vishay Siliconix. It utilizes BiCMOS wafer fabrication technology to operate on single supplies from 3 V to 12 V or dual supplies of ± 3 V to ± 6 V. The device features an on-resistance (RDS(on)) of 1.7 Ω, turn-on time (tON) of 42 ns, and turn-off time (tOFF) of 28 ns. It offers minimal insertion loss (-3 dB at 190 MHz), excellent crosstalk performance, and 2000 V ESD protection. The component is housed in a 16-pin TSSOP package with an operating temperature range of -40 °C to +85 °C.
