DG303BDY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303BDY-T1-E3 is a monolithic CMOS analog switch from the Vishay Siliconix DG303B family, housed in a 14-SOIC surface-mount package. It features two independent SPDT (Single Pole Double Throw) channels with low on-resistance and fast switching speeds. The device supports single or dual power supplies ranging from ±7 V to ±22 V, accommodating full rail-to-rail analog signal ranges up to ±15 V. Key electrical parameters include a maximum drain-source on-resistance of 50 Ω at room temperature, turn-on time of 150 ns, and turn-off time of 130 ns. Designed for precision applications, it offers latch-up protection, low power consumption, and CMOS compatibility.
