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 that 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 translates 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.
