GENERAL DESCRIPTION
The ADG3304 is a bidirectional logic level translator that contains four bidirectional channels. It can be used in multivoltage digital system applications, such as data transfer, between a low voltage digital signal processing controller and a higher voltage device using SPI and MICROWIRE interfaces. The internal architecture allows the device to perform bidirectional logic level translation without an additional signal to set the direction in which the translation takes place.
