GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The ADG3245 is a 2.5 V or 3.3 V, 8-bit, 2-port digital switch.

It 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.

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. 20-lead TSSOP and LFCSP (4 mm × 4 mm) packages

The switches are enabled by means of the Bus Enable (BE) input

signal. These digital 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 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. In addition to this, a

level translating select pin (SEL) is included. When SEL is low,

_CCis reduced internally, allowing for level translation between

3.3 V inputs and 1.8 V outputs. This makes the device suited to

applications requiring level translation between different supplies,

such as converter to DSP/microcontroller interfacing.
