GENERAL DESCRIPTION
The ADG3241 is a 2.5 V or 3.3 V, single digital switch. It is
designed on a low voltage CMOS process, which provides low
power dissipation yet gives high switching speed and very low on
resistance. This allows the input to be connected to the output
without additional propagation delay or generating additional
ground bounce noise.
The switch is enabled by means of the bus enable (BE) input
signal. This digital switch allows a bidirectional signal 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.
