About Voltage Level Translators

Voltage level translators are essential interface components that resolve compatibility issues in mixed-voltage electronic systems. They enable communication between devices operating at different logic levels—such as connecting legacy 3.3V peripherals to modern 1.8V processors—without signal degradation or component damage. Proper voltage translation prevents data corruption and extends system lifespan.

Modern translators like the SN74AVC2T244 series feature auto-direction sensing and ultra-low quiescent current, making them indispensable for portable electronics. Their bidirectional capabilities and high-speed operation support critical functions in communication buses like I²C, SPI, and GPIO interfaces. Selecting the correct voltage translator ensures system reliability while simplifying PCB design.

Packaging Options

Available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® packaging to suit various production requirements. All formats include moisture-sensitive packaging with industry-standard desiccant protection.

Frequently Asked Questions

Q: What’s the difference between unidirectional and bidirectional translators?
A: This unidirectional model (74AVC2T244) requires direction control pins, while bidirectional variants auto-detect signal flow. Choose based on system control requirements.

Q: Can this IC handle 5V to 1.8V translation?
A: No. The maximum supported voltage is 3.6V on both ports. For 5V systems, consider TI’s 74LVC or 74AXC families.

Q: Is external pull-up/pull-down needed for I²C applications?
A: Yes. Like most voltage translators, external resistors are required for open-drain buses like I²C.

Q: What’s the power consumption in standby mode?
A: Typical I_CC is <2µA when disabled, making it suitable for battery-powered devices.

Q: Are evaluation boards available for this component?
A: Yes. PCX provides access to TI’s DQE evaluation module documentation upon request.

Q: How does this compare to the non-DQER version?
A: The “DQER” suffix denotes the 8-X2SON package. Functionality is identical to other 74AVC2T244 variants.
