MAX13044E

The MAX13042E–MAX13045E 4-channel, bidirectional level translators provide the level shifting necessary for 100Mbps data transfer in multivoltage systems. The MAX13042E–MAX13045E are ideally suited for level translation in systems with four channels. Externally applied voltages, V_CC and V_L, set the logic levels on either side of the device. Logic signals present on the V_L side of the device appear as a high-voltage logic signal on the V_CC side of the device and vice-versa.

The MAX13042E–MAX13045E 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 30µA current source, allowing the MAX13042E–MAX13045E to be driven by either push-pull or open-drain drivers.

The MAX13042E–MAX13045E feature an enable (EN) input that places the devices into a low-power shutdown mode when driven low. The MAX13042E–MAX13045E feature an automatic shutdown mode that disables the part when V_CC is less than V_L. The state of I/O V_CC_ and I/O V_L_ during shutdown is chosen by selecting the appropriate part version. (See the Ordering Information/Selector Guide in the full data sheet).

The MAX13042E–MAX13045E 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 MAX13042E–MAX13045E are available in 12-bump UCSP™ (1.54mm x 2.12mm) and 14-pin TDFN (3mm x 3mm) packages, and operate over the extended -40°C to +85°C temperature range.
