1.62V to 3.6V Improved High-Speed LLT

High-Speed (100Mbps), 4-Channel Translators

Please check latest availability status for a specific part variant.


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, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side of the device appear as a high-voltage logic signal on the VCC 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 VCC or VL 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 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 the Ordering Information/Selector Guide in the full data sheet).

The MAX13042E–MAX13045E 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 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.
