VISHAY DG408LEDQ-T1-GE3

The DG408LE, DG409LE are monolithic analog multiplexers / demultiplexers designed to operate on single and dual supplies. Single supply voltage ranges from 3V to 16 V while dual supply operation is recommended with ±3 V to ±8 V. The DG408LE is an 8 channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined by a 3 bit binary address (A₀, A₁, A₂). The DG409LE is a dual 4 channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its 2 bit binary address (A₀, A₁). Break-before-make switching action to protect against momentary crosstalk between adjacent channels. An on channel conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails. An enable (EN) function allows the user to reset the multiplexer / demultiplexer to all switches off for stacking several devices. All control inputs, address (Ax) and enable (EN) are TTL compatible over the full specified operating temperature range. The DG408LE, DG409LE feature low on-resistance, fast switching time, and low leakage. They are ideal for data acquisition, control and automation, test instrument, and healthcare products. The DG408LE, DG409LE has an internal regulator powers the logic circuit. Such design reduces device power consumption and makes them ideal for battery operated applications. The DG408LE, DG409LE are available in TSSOP16, SOIC16, and QFN16 packages.
