MAX13043EEBC+T

Translators, Level Shifters Overview

The MAX13043EEBC+T is a four-channel bidirectional voltage level translator from the MAX13042E–MAX13045E series, manufactured by Analog Devices Inc./Maxim Integrated. It supports data transfer rates up to 100Mbps in multivoltage systems. The device operates with VCC voltages ranging from +2.2V to +3.6V and VL voltages from +1.62V to +3.2V. It features an enable (EN) input for low-power shutdown mode and automatic shutdown when VCC is less than VL. During shutdown, I/O VL_ lines enter a high impedance state while I/O VCC_ lines are pulled down to ground via an internal resistance. The component is housed in a 12-bump UCSP package measuring 1.54mm x 2.12mm and operates over an extended temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Four bidirectional channels provide level shifting between low-voltage ASICs/PLDs and higher voltage systems.
• Internal pullup current sources allow operation with push-pull or open-drain drivers without external resistors.
• Enable input facilitates low-power shutdown, while automatic shutdown occurs when VCC falls below VL.
• Integrated rise/fall-time accelerators ensure fast transitions for high-speed data integrity.

Translators, Level Shifters Applications

• CMOS logic-level translation
• Low-voltage ASIC level translation
• SPI and MICROWIRE level translation
• Portable POS systems
• Telecommunications equipment

Translators, Level Shifters Procurement Notes

Verify the specific part number suffix against the manufacturer's ordering guide to confirm the shutdown state configuration. The MAX13043 variant specifies high impedance on I/O VL_ and pulldown on I/O VCC_ during shutdown. Ensure compatibility with the required system voltage levels and thermal management requirements for the UCSP package before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional translation between 1.62V–3.2V and 2.2V–3.6V domains at speeds up to 100Mbps. Choose the MAX13043 specifically if the application requires the I/O VL_ lines to remain high impedance and the I/O VCC_ lines to be actively pulled low during power-down or enable deactivation states.

Translators, Level Shifters Part Context

This device belongs to the MAX13042E–MAX13045E family of improved high-speed logic-level translators. These components are designed to bridge voltage gaps in portable and telecommunications applications. The MAX13043 variant is distinguished by its specific output behavior during shutdown modes compared to other members of the series, such as the MAX13042 or MAX13044.

Translators, Level Shifters Replacement Considerations

Direct substitutes within the same family include the MAX13042EEBC+T, MAX13044EEBC+T, and MAX13045EEBC+T. Selection depends on the required I/O state during shutdown; the MAX13042 maintains high impedance on both sides, while the MAX13044 and MAX13045 offer different pulldown configurations for the I/O VCC_ lines.

Translators, Level Shifters FAQ

What is the state of the I/O pins during shutdown for the MAX13043?

During shutdown, the I/O VL_ lines enter a high impedance state, while the I/O VCC_ lines are pulled down to ground through an internal resistance.

Can the MAX13043 drive open-drain signals?

Yes, the device includes internal pullup current sources that allow it to be driven by either push-pull or open-drain drivers without the need for external pullup resistors.
