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 VCCApatible logic signals applied to the A pin appear as VCCYpatible levels on the Y pin. Similarly, VCCY-patible logic levels applied to the Y pin appear as VCCA-patible 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 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 ADG3301 is available in a pact 6-lead SC70 package and is guaranteed to operate over the 1.15 V to 5.5 V supply voltage range and extended - 40°C to +85°C temperature range.
