It can be used in multivoltage A side and the Y side pins. When the EN pin is pulled low, the digital system applications, such as data transfer, between a low terminals on both sides of the device are in the high impedance voltage digital signal processing controller and a higher voltage state. The EN pin is referred to the VCCA supply voltage and device using SPI and MICROWIRE interfaces. The internal driven high for normal operation. architecture allows the device to perform bidirectional logic The ADG3304 is available in compact 14-lead TSSOP, 12-ball level translation without an additional signal to set the direction WLCSP, and 20-lead LFCSP. It is guaranteed to operate over in which the translation takes place. the 1.15 V to 5.5 V supply voltage range.
