GENERAL DESCRIPTION
The ADG3242 is a 2.5 V or 3.3 V, 2-bit, 2-port, common control
digital switch. It is designed on a low voltage CMOS process, and
provides low power dissipation, yet gives high switching speed
and very low on resistance. This allows the inputs to be connected
to the outputs without additional propagation delay or generating
additional ground bounce noise.
These switches are enabled by means of a common 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 oper-
ated from a 2.5 V supply and 2.5 V inputs are applied, the device
translates the outputs to 1.8 V. In addition, 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 suitable for applications
requiring level translation between different supplies, such as
converter to DSP/microcontroller interfacing.
