Overview
The ADG3231BRJZ-REEL7, produced by Analog Devices Inc., is a single-channel level translator designed to facilitate communication between digital devices operating at different supply voltages. This device is fabricated on a submicron process and is guaranteed to operate over a supply range of 1.65 V to 3.6 V. The ADG3231 is particularly useful in applications where level translation is necessary, such as in mixed-voltage systems. It features a unidirectional signal path, allowing data to flow only from the input (A) to the output (Y), and supports both up and down level translation depending on the supply voltage combinations.
