GENERAL DESCRIPTION
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, 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.
