The ADG3300 is bidirectional logicLevel translators, built-in 8 bidirectional channels, can be used for multi-voltage digital systems, such as low-voltage DSP/controller and high-voltage device data transmission. The device's internal structure allows bidirectional logic-level translation without the need for additional signals to set the conversion direction.
By applying to VCCA, which can set the logic level at A of the device, 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 provides three-state operation of the Y-terminal pin. When the enable pin (EN) is pulled low, pins A1 through A8 are pulled low by an internal 6 kΩ resistor, while the Y pin is in a high impedance state. The EN pin starts with VCCAThe supply voltage is referenced and driven high in normal operating mode.
The ADG3300 is available in a compact 20-lead TSSOP package with a guaranteed operating voltage range of 1.15 V to 5.5 V and an operating temperature range of −40°C to +85°C.
