GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG3231 is a Level Translator designed on a sub micron process which 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 bi-directional level translation, i.e. it translates low voltages to higher voltages and vice versa. The signal path is uni-directional, data may only flow from A1 to Y1. This type of device may be used in applications requiring communication between devices operating from different supply levels. The level translator is packaged in one of the smallest footprints available for its pin count. The 6 lead SOT23 package requires only 5.28mm2 max board space.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this speci*cation is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG3231 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

DESCRIPTION
The ADG3231 is a level translating device designed on a sub micron process which 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 uni-directional level translation. The ADG3231 can translate low voltages to higher voltages and vice versa.
A1 Input
Figure 1. Propagation Delay
The input A1 is capable of accepting inputs outside the VCC1 supply range. For example, the VCC1 supply applied to the device could be 1.8V while the preceding device could be supplied from a 2.5V or 3.3V supply rail, there are no internal diodes to the supply rails, so the ADG3231 can handle inputs above the supply, but inside the absolute maximum ratings stated.
Normal Operation
The signal path is from A1 to Y1, the device will level translate the signal applied to A1 to a VCC1 logic level (this level translation can be either to a higher or lower supply) and route the signal to the Y1 output, which will have standard VOL/VOH levels for VCC2 supplies. The three supplies in Figures 4 & 5 may be any combination of supplies, i.e. VCC0, VCC1 and VCC2 may be any combination of supplies, for example: 1.8, 2.5, 3.3V.
