ADG3304 is a bidirectional logic level converter with 4 built-in bidirectional channels. It can be used for multi-voltage digital systems, such as data transfer between low-voltage DSPs/controllers and high-voltage devices using SPI and MICROWIRE interfaces. The internal structure of the device allows for bidirectional logic level conversion without the need for additional signals to set the conversion direction.
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, the 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. The EN pin is based on the VCCA supply voltage and is driven high in normal operating mode.
ADG3304 is available in compact 14-pin TSSOP and 12-pin WLCSP packages 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.
