DG408LEDQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408LEDQ-T1-GE3 is an eight-channel single-ended analog multiplexer from Vishay Siliconix, housed in a 16-pin TSSOP package. It operates on single supplies of 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device features a typical on-resistance of 17 Ω and maximum leakage current of 1 nA. Power consumption is limited to 6 μA with the enable pin active. Switching times include a turn-on time of 55 ns and turn-off time of 36 ns at ±5 V. It includes break-before-make switching and TTL/CMOS compatible logic inputs.
