GENERAL DESCRIPTION
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.
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
CC
is
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.
