GENERAL DESCRIPTION
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.
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,
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.
