DESCRIPTION

The ADG3232 is a mux level translating device designed on a

submicron process that operates from supplies as low as 1.65 V.

The device is guaranteed for operation over the supply range

1.65 V to 3.6 V. It operates from two supply voltages, allowing

bidirectional level translation, i.e., it translates lower voltages to

higher voltages and vice versa.The signal path is unidirectional,

meaning data may only flow from A toY.

A1 and EN Input

value of the supply being used. Both these inputs (A1 and EN)

There are no internal diodes to the supply rails on these pins, so

they can handle inputs above the supply but inside the absolute

maximum ratings.

Operation

Figure 3 shows the ADG3232 in a typical application; the signal

paths are from A1 or A2 toY. The device will level translate the signal

be either to a higher or a lower supply) and route the signal to the

The supplies in Figure 3 may be any combination of supplies, e.g.,
