74AUP1T45GS,132

Overview

The Nexperia 74AUP1T45GS,132 is a single-channel dual-supply voltage level translator housed in an XSON-6 (SOT1202) surface-mount package. It operates within a supply voltage range of 0.8 V to 3.6 V for both ports A and B. The device features automatic direction sensing, eliminating the need for direction control pins. It supports bidirectional data transfer between different voltage domains with propagation delays typically around 5 ns at 1.8 V. The component complies with JEDEC standards for low-voltage CMOS logic and includes Ioff circuitry to prevent excessive current draw during partial power-down states.

Feature Summary

• Automatic bidirectional direction sensing without external control pins
• Dual-supply operation supporting independent voltage domains on port A and port B
• Ioff circuitry prevents backflow current when the device is partially powered down
• Schmitt-trigger action on inputs provides noise immunity and tolerance for slow input rise/fall times

Applications

• Connecting microcontrollers operating at one logic voltage to peripherals at another
• Interfacing memory devices across different voltage levels in embedded systems
• Level shifting in portable battery-powered consumer electronics
• Bidirectional data translation in mixed-voltage digital communication buses

Procurement Notes

Verify the specific suffix '132' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the XSON-6 footprint matches your PCB layout guidelines. Ensure the design accounts for the maximum operating temperature rating of +125°C if used in high-thermal environments. Cross-reference the manufacturer part number with official distributor catalogs to confirm current production status and availability.

Selection Notes

Select this component when a single-channel, bidirectional level shifter with automatic direction detection is required. It is suitable for applications where minimizing pin count is critical due to the absence of direction control inputs. Consider the XSON-6 package size constraints and the 0.8 V to 3.6 V operating range compatibility with your system's voltage rails. Verify that the input signal characteristics align with the Schmitt-trigger input requirements for proper noise rejection.

Part Context

This part belongs to the Nexperia 74AUP series, which utilizes advanced ultra-low power CMOS technology. The AUP family is designed for applications requiring low static and dynamic power consumption while maintaining high noise immunity. The 74AUP1T45 specifically addresses voltage translation needs in modern low-voltage digital systems, offering a compact solution compared to discrete resistor-based level shifting methods.

Replacement Considerations

Check for direct equivalents such as the SN74AVC1T45 from Texas Instruments or similar single-channel dual-supply translators from other manufacturers. Ensure any substitute maintains the same XSON-6 or compatible package outline and supports the required voltage ranges. Verify that the replacement also offers automatic direction sensing and Ioff functionality if partial power-down support is needed.
