1.65 V to 3.6 V, Single-Channel Level Translator in SOT-23 Package Data Sheet ADG3231 FEATURES FUNCTIONAL BLOCK DIAGRAM V V Operates from 1.65 V to 3.6 V supply rails CC1 CC2 Unidirectional signal path Up/down level translation A Y Ultracompact 6-lead SOT-23 package Output short-circuit protection LVTTL-/CMOS-compatible inputs GND Figure 1. APPLICATIONS Level translation in PDAs Handsets MP3 players against current overload, which can occur when the Y pin is GENERAL DESCRIPTION accidentally shorted to the V or GND rails. CC2 The ADG3231 is a single-channel level translator designed on a submicron process that is guaranteed to operate over the 1.65 V The ADG3231 is available in the SOT-23 (2.8 mm 2.9 mm to 3.6 V supply range. The device can be used in applications 1.3 mm) ultracompact package, making the part ideal for requiring communication between digital devices operating applications where space is critical. from multiple supply voltages. The logic levels on each side of PRODUCT HIGHLIGHTS the device are set by the two supply voltages, V for A and CC1 V for Y. The signal path is unidirectional, meaning data can 1. Up/down level translation. CC2 flow only from A to Y. 2. Guaranteed to operate with any supply combination within The ADG3231 can operate with any combination of V the 1.65 V to 3.6 V range. CC1 and V supply voltages within the 1.65 V to 3.6 V range, CC2 3. Output short-circuit protection. allowing the part to perform either up (V < V ) or down CC1 CC2 (V > V ) level translation. The output stage is protected CC1 CC2 4. Available in ultracompact SOT-23 package. Rev. C Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
