Overview
The ADG3304SRU-EP-RL7 is a bidirectional logic level translator produced by Analog Devices Inc. This component is designed for use in multivoltage digital system applications, enabling seamless data transfer between devices operating at different voltage levels. It features four bidirectional channels, making it ideal for various interfaces such as SPI and MICROWIRE.
The device operates without the need for an additional direction-setting signal, allowing for automatic bidirectional logic level translation. The voltage applied to VCCA sets the logic levels on the A side, while VCCY sets the levels on the Y side. The enable pin (EN) provides three-state operation, placing the terminals in a high impedance state when pulled low.
