The ADG3232 is a 2:1 multiplex
Level translators, manufactured on a submicron process with supply voltages as low as 1.65 V. The guaranteed operating voltage range is 1.65 V to 3.6 V. It operates with two supply voltages and can perform bidirectional level translation, i.e. low-to-high-voltage and high-to-low. The signal path is unidirectional, and data can only flow from A to Y.
These devices can be used for device-to-device communication with different operating levels.
This multiplexed level translator is available in one of the smallest pin-count packages of this kind. The 8-pin SOT23 package requires only 8.26 mm2Board space.
