The ADG3308 is bidirectionalLevel translatorsBuilt-in 8 bidirectional channels, which can be used for multi-voltage digital systems, such as data transmission between low-voltage DSP controllers and high-voltage devices. The internal structure of the device allows bidirectional level shifting to be performed without the need for additional signals to set the conversion direction.
By applying to VCCAThe voltage can be set at the A terminal of the deviceLogic level，VCCYIt is responsible for setting the logic level at the Y terminal. To ensure proper operation, VCCAMust always be below VCCY。 V applied to the A terminal of the deviceCCACompatible with logic signals, V on the Y-sideCCYCompatibility levels appear. Similarly, V is applied to the Y terminal of the deviceCCYCompatible with logic levels, V at the A sideCCACompatible logic levels appear.
The enable pin (EN) provides tri-state operation for the A and Y terminal pins. When the EN pin is pulled low, the pins at both ends are in a high impedance state. In normal operation, EN should be driven high.
The ADG3308 is available in compact 20-lead TSSOP and 20-lead LFCSP packages. The EN pin starts with VCCYThe supply voltage is the reference.
The ADG3308 has a guaranteed operating voltage range of 1.15 V to 5.5 V and an operating temperature range of −40°C to +85°C.
