Description

The ADG3247 is a 2.5 V or 3.3 V 16-bit, 2-port digital switch. ADG3247 is designed on Analog Devices' low voltage CMOS process,which provides low power dissipation yet gives high switching speed and very low on resistance, allowing inputs to be connected to outputs without additional propagation delay or generating additional ground bounce noise.

This allows ADG3247 to be used as two 8-bit digital switches or one 16-bit bus switch. These bus switches allow bidirectional signals to be switched when ON. In the OFF condition, signal levels up to the supplies are blocked. This device is ideal for applications requiring level translation. When operated from a 3.3 V supply, level translation from 3.3 V inputs to 2.5 V outputs occurs. Similarly, if the device is operated from a 2.5 V supply and 2.5 V inputs are applied, the device will translate the outputs to 1.8 V.
