The ADG3308-1 is a bidirectional level translator containing eight bidirectional channels. They can be used in multivoltage digital system applications such as a data transfer between a low voltage DSP controller and a higher voltage device. The internal architecture allows the device to perform bidirectional level translation without an additional signal to set the direction in which the translation takes place.The voltage applied to VCCAsets the logic levels on the A side of the device, and VCCYsets the levels on the Y side. For proper operation, VCCAmust always be less than VCCY. The VCCA-compatible 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. For normal operation, EN should be driven high.The ADG3308-1 is available in a 20-ball WLCSP. The EN pin is referred to the VCCAsupply voltage.The ADG3308-1 guaranteed to operate over the 1.15 V to 5.5 V supply voltage range and the extended −40°C to +85°C temperature range.Product HighlightsBidirectional logic level translation.Fully guaranteed over the 1.15 V to 5.5 V supply range.No direction pin.Packages: 20-ball WLCSP.ApplicationsLow voltage ASIC level translationSmart card readersCell phones and cell phone cradlesPortable communication devicesTelecommunications equipmentNetwork switches and routersStorage systems (SAN/NAS)Computing/server applicationsGPSPortable POS systemsLow cost serial interfaces
