ADG3308 is a bidirectional level converter with 8 built-in bidirectional channels that can be used for multi-voltage digital systems, such as data transmission between low-voltage DSP controllers and high-voltage devices. The internals of the device allow for bidirectional level conversion without the need for additional signals to set the direction of the transition.
The voltage applied to the VCCA sets the logic level on the A side of the device, while the VCCY sets the logic level on the Y side. To ensure proper operation, VCCA must always be below VCCY. The VCCA-compatible logic signal applied to the A-side of the device appears at the VCCY-compatible level on the Y-side. Similarly, the VCCY-compatible logic level applied to the Y side of the device appears as a VCCA-compatible logic level on the A side.
The enable pin (EN) provides a three-state operation mode for both A-side and Y-terminal pins. When the EN pin is pulled down, the pins at both ends are in a high impedance state. When working properly, EN should be driven to high level.
ADG3308 is available in compact 20-pin TSSOP and 20-pin LFCSP packages. The EN pin is based on the VCCY supply voltage.
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.
