Propagation Delay DESCRIPTION The ADG3231 is a level translating device designed on a submicron process that 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 bidirectional level translation, i.e., it translates low voltages to high voltages and vice versa. The signal path is unidirectional, meaning data may only flow from A to Z. A1 Input The A1 input is capable of accepting inputs outside the VCC1 supply range. For example, the VCC1 supply applied to the device could be 1.8 V while the preceding device could be supplied from a 2.5 V or 3.3 V 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 to either a higher or a lower supply) and route the signal to the Y1 output, which will have standard VOL/VOH levels for VCC2 supplies. The supplies in Figure 2 may be any combination of supplies, e.g., VCC1 and VCC2 may be anywhere in the range of 1.65 V to 3.6 V.
