MAX13057E

19-4813; Rev 0; 7/09 1.62V to 3.6V, 8-Channel, High-Speed LLT General Description The MAX13055E–MAX13058E 8-channel, bidirectional level translators provide the level shifting necessary for 100Mbps data transfer in multivoltage systems. The MAX13055E–MAX13058E are ideal for level translation in systems with 8 channels. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. Logic-high signals presented on the VL side of the device appear as a logic-high signal on the VCC side of the device and vice versa. The MAX13055E–MAX13058E operate at full speed with external drivers that source as little as 4mA output current or larger. Each input/output (I/O) channel is pulled up to VCC or VL by an internal 40µA current source, allowing the MAX13055E–MAX13058E to be driven by either push-pull or open-drain drivers. The MAX13055E–MAX13058E feature an enable (EN) input to place the device into a low-power shutdown mode when driven low. In addition, the MAX13055E– MAX13058E feature an automatic shutdown mode that disables the part when V CC is less than V L . Each device has a different I/O VL_ and I/O VCC_ state during shutdown mode (see the Ordering Information/Selector Guide). The MAX13055E–MAX13058E operate with VCC voltages from +2.2V to +3.6V and VL voltages from +1.62V to +3.2V, making them ideal for data transfer between lowvoltage ASIC/PLDs and higher voltage systems. The MAX13055E–MAX13058E are available in 0.4mm pitch, 24-bump WLP and 28-pin...
