DG4157DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG4157DN-T1-E4 is a single-channel SPDT analog switch manufactured by Vishay Siliconix, housed in a miniQFN-6L surface-mount package. It operates on a single supply voltage ranging from 1.65 V to 5.5 V with a maximum power dissipation of 160 mW. The device features a maximum on-resistance of 2.5 Ohms and supports a DC switch current of 200 mA. Switching performance includes a maximum turn-on time of 55 ns and a maximum turn-off time of 27 ns. It functions within an operating temperature range of -40°C to +85°C and draws a maximum supply current of 500 nA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated power-down protection circuit prevents abnormal current flow between the COM pin and V+ during power-off conditions.
• Supports control logic input voltages exceeding the positive supply rail (V+) up to 5.5 V, ensuring compatibility with higher-voltage digital interfaces.
• Features break-before-make switching characteristics to prevent signal shorting during channel transitions.
