APPLICATIONS

A GND Y VCC1 VCC2 03298-001 Figure 1. GENERAL DESCRIPTION The ADG3231 is a single-channel level translator designed on a submicron process that is guaranteed to operate over the 1.65 V to 3.6 V supply range. The device can be used in applications requiring communication between digital devices operating from multiple supply voltages. The logic levels on each side of the device are set by the two supply voltages, V CC1 for A and VCC2 for Y . The signal path is unidirectional, meaning data can flow only from A to Y . The ADG3231 can operate with any combination of VCC1 and VCC2 supply voltages within the 1.65 V to 3.6 V range, allowing the part to perform either up (VCC1 < VCC2) or down (VCC1 > VCC2) level translation. The output stage is protected against current overload, which can occur when the Y pin is accidentally shorted to the VCC2 or GND rails. The ADG3231 is available in the SOT-23 (2.8 mm × 2.9 mm × 1.3 mm) ultracompact package, making the part ideal for applications where space is critical. PRODUCT HIGHLIGHTS 1. Up/down level translation. 2. Guaranteed to operate with any supply combination within the 1.65 V to 3.6 V range. 3. Output short-circuit protection. 4. Available in ultracompact SOT-23 package.
