GENERAL DESCRIPTION
The ADG3301 is a single-channel, bidirectional logic level translator. It can be used in multivoltage digital system applications such as data transfer between a low voltage DSP/controller and a higher voltage device. 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 pin appear as VCCYcompatible levels on the Y pin. Similarly, VCCY-compatible logic levels applied to the Y pin appear as VCCA-compatible logic levels on the A pin. The enable pin (EN) provides three-state operation on both the A pin and the Y pin. When the device enable pin is pulled low, the terminals on both...
