The ADG3243 is a 2.5 V or 3.3 V, 2-bit, 2-port digital switch with individual channel control. It is designed on a low voltage CMOS process, which provides low power dissipation yet gives high switching speed and very low on resistance. This allows the inputs to be connected to the outputs without additional propagation delay or generating additional ground bounce noise.

The switches are enabled by means of the bus enable ()input signal. This digital switch allows a bidirectional signal 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 is allowed. 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. This makes the device suited to applications requiring level translation between different supplies, such as converter to DSP/microcontroller interfacing.
