GENERAL DESCRIPTION  
The ADG3304 is a bidirectional logic level translator that con-  
tains 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.  
The enable pin (EN) provides three-state operation on both the  
A side and the Y side pins. When the EN pin is pulled low, the  
terminals on both sides of the device are in the high impedance  
state. The EN pin is referred to the VCCA supply voltage and  
driven high for normal operation.  
The ADG3304 is available in compact 14-lead TSSOP, 12-ball  
WLCSP, and 20-lead LFCSP. It is guaranteed to operate over  
the 1.15 V to 5.5 V supply voltage range.  
The voltage applied to VCCA sets the logic levels on the A side of  
the device, while VCCY sets the levels on the Y side. For proper  
operation, VCCA must always be less than VCCY. The VCCA-com-  
patible logic signals applied to the A side of the device appear as

CCY-compatible levels on the Y side. Similarly, VCCY-compatible  
logic levels applied to the Y side of the device appear as VCCA  
compatible logic levels on the A side.
