GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
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, 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.
