1. DESCRIPTIONS

The ADG3304BCPZ-REEL7 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. 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 VCCAcompatible logic signals applied to the A side of the device appear as VCCY-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. 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 ADG3304BCPZ-REEL7 is available in compact 14-lead TSSOP package.
