Description

The MAX13030E–MAX13035E 6-channel, bidirectionallevel translators provide the level shifting necessary for100Mbps data transfer in multivoltage systems. TheMAX13030E–MAX13035E are ideally suited for memory-card level translation, as well as generic level translation in systems with six channels. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side ofthe device appear as a higher voltage logic signal onthe VCC side of the device and vice versa. TheMAX13035E features a CLK_RET output that returns thesame clock signal applied to the CLK_VL input.The MAX13030E–MAX13035E operate at full speedwith external drivers that source as little as 4mA outputcurrent. Each I/O channel is pulled up to VCC or VL byan internal 30μA current source, allowing theMAX13030E–MAX13035E to be driven by either push-pullor open-drain drivers.The MAX13030E–MAX13034E feature an enable (EN)input that places the device into a low-power shutdownmode when driven low. The MAX13030E–MAX13035Efeatures an automatic shutdown mode that disables thepart when VCC is less than VL. The state of I/O VCC_ and I/O VL_ during shutdown is chosen by selecting the appropriate part version (see Ordering Information/Selector Guide located within the full datasheet).The MAX13030E–MAX13035E accept VCC voltagesfrom +2.2V to +3.6V and VL voltages from +1.62V to+3.2V, making them ideal for data transfer betweenlow-voltage ASIC/PLDs and higher voltage systems.The MAX13030E–MAX13035E are available in 16-bumpUCSP (2mm x 2mm) and 16-pin TQFN (4mm x 4mm)packages, and operate over the extended -40°C to+85°C temperature range.ApplicationsMemory Stick Card Level TranslationMiniSD Card Level TranslationMMC Level TranslationSD Card Level TranslationTransFlash® Level Translation
