general description the max13055e?ax13058e 8-channel, bidirectional level translators provide the level shifting necessary for 100mbps data transfer in multivoltage systems. the max13055e?ax13058e are ideal for level translation in systems with 8 channels. externally applied voltages, v cc and v l , set the logic levels on either side of the device. logic-high signals presented on the v l side of the device appear as a logic-high signal on the v cc side of the device and vice versa. the max13055e?ax13058e 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 v cc or v l by an internal 40? current source, allowing the max13055e?ax13058e to be driven by either push-pull or open-drain drivers. the max13055e?ax13058e 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 v l_ and i/o v cc_ state during shutdown mode (see the ordering information/selector guide ). the max13055e?ax13058e operate with v cc voltages from +2.2v to +3.6v and v l voltages from +1.62v to +3.2v, making them ideal for data transfer between low- voltage asic/plds and higher voltage systems. the max13055e?ax13058e are available in 0.4mm pitch, 24-bump wlp and 28-pin tqfn (3.5mm x 5.5mm) pack- ages. the max13055e?ax13058e operate over the extended -40? to +85? temperature range. applications features ? compatible with 4ma input drivers or larger ? 100mbps guaranteed data rate ? 8 bidirectional channels ? +1.62v v l +3.2v and +2.2v v cc +3.6v supply voltage range ? 24-bump wlp (0.4mm pitch) lead-free package ? 28-pin tqfn (3.5mm x 5.5mm) lead-free package ? extended esd protection on i/o v cc lines 15kv per human body model 15kv iec 61000-4-2 air discharge 8kv iec 61000-4-2 contact discharge max13055e?ax13058e 1.62v to 3.6v, 8-channel, high-speed llt ________________________________________________________________ maxim integrated products 1 19-4813; rev 0; 7/09 ordering information/selector guide part i/o v l _ state during shutdown i/o v cc _ state during shutdown temp range pin-package max13055e ewg+ open drain open drain -40? to +85? 24 wlp max13055eeti+ open drain open drain -40? to +85? 28 tqfn-ep* for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim's website at www.maxim-ic.com. low-voltage asic level translation smart card readers camera modules portable pos systems portable communication devices cell phones gps telecomm equipment gnd gnd gnd +1.8v system controller +3.3v system v l v cc i/o v l_ i/o v cc_ data data +3.3v +1.8v en en 1 f 0.1 f 0.1 f max13055e max13058e 8 8 typical operating circuit pin configurations appear at end of data sheet. ordering information/selector guide continued at end of data sheet. + denotes a lead(pb)-free/rohs-compliant package. * ep = exposed pad. evaluation kit available
