GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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 propa-

gation delay or generating additional ground bounce noise.

1. 3.3 V or 2.5 V supply operation.

2. Extremely low propagation delay through switch.

3. 4.5 Ω switches connect inputs to outputs.

4. Level/voltage translation.

5. Tiny SOT-23 package.

The switches are enabled by means of the bus enable (BEx) 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.
