GENERAL DESCRIPTION

The ADG3246 is a 2.5 V or 3.3 V, 10-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.

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 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 ADG3246 has a level

translating select pin (SEL). When SEL is low, VCC is 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.
