DG9251EN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9251EN-T1-E4 is an 8-channel multiplexer switch IC manufactured by Vishay / Siliconix. It features a 1 x 8:1 configuration, routing one of eight inputs to a single output. The device operates within a supply voltage range of 2.7 V to 12 V and supports dual supplies from 2.5 V to 5 V. It utilizes a QFN-16 package for surface mount installation. Key electrical parameters include a maximum on-resistance of 265 Ohms, a bandwidth of 450 MHz, and typical off-isolation of -67 dB. Power dissipation is rated at 525 mW, with operating temperatures spanning from -40°C to +125°C.
