GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The ADG3247 is a 2.5 V or 3.3 V 16-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. 40-lead 6 mm ϫ 6 mm LFCSP and 38-lead TSSOP packages

The ADG3247 is organized as dual 8-bit bus switches with

separate Bus Enable (BEx) inputs. This allows the device 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. In addition to this, the ADG3247

has a level translating select pin (SEL). When SEL is low, V_CCis

reduced internally, allowing for level translation between 3.3 V

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

cations requiring level translation between different supplies, such

as converter to DSP/microcontroller interfacing.
