74AUP1T97UKAZ

Overview

The Nexperia 74AUP1T97UKAZ is a low-power configurable gate with voltage-level translation capabilities, housed in a 6-WLCSP package. It operates within a supply voltage range of 2.3 V to 3.6 V and supports unidirectional level shifting between 1.8 V and 3.6 V domains. The device features Schmitt-trigger inputs for noise immunity and includes I_OFF circuitry to prevent backflow current during partial power-down states. Designed for automotive applications, it holds AEC-Q100 qualification and functions across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Configurable multiple-function logic gate supporting MUX, AND, OR, NAND, NOR, inverter, and buffer modes via 3-bit input selection
• Integrated voltage-level translator enabling interface between 1.8 V and 3.6 V logic systems
• Schmitt-trigger inputs provide high noise immunity and tolerance for slow signal transitions
• I_OFF circuitry ensures safe partial power-down operation by disabling outputs to prevent damaging backflow currents

Applications

• Automotive engine control units requiring robust logic interfacing
• Body control modules managing mixed-voltage sensor networks
• Transmission control units utilizing bidirectional data buses
• Electronic instrument clusters connecting disparate voltage domains

Procurement Notes

Verify component authenticity through official Nexperia channels or authorized distributors. Confirm the specific suffix UKAZ corresponds to the 6-WLCSP (0.65x0.44) package variant. Ensure compliance with RoHS3 and REACH regulations as stated in the datasheet. Check for any product change notices regarding labeling or assembly updates prior to final procurement decisions.

Selection Notes

Select this component when designing circuits that require both configurable logic functionality and automatic voltage translation between 1.8 V and 3.6 V rails. The small WLCSP footprint makes it suitable for space-constrained automotive PCB layouts. Consider the AEC-Q100 Grade 1 qualification if the application demands high reliability under extreme thermal conditions up to 125 °C.

Part Context

This part belongs to the Nexperia 74AUP series of ultra-low-power CMOS logic devices. The 74AUP1T97 family specifically combines configurable gate logic with single-channel voltage translation. While the UKAZ variant utilizes a WLCSP package, other versions like GM use XSON packages. All variants share the same core electrical characteristics and logical configuration options defined by the base 74AUP1T97 specification.

Replacement Considerations

The 74AUP1T97GXZ is listed as a direct substitute for the discontinued 74AUP1T97UKAZ. Both parts offer identical logical functions and voltage translation capabilities. Verify that the GXZ package (X2SON6) fits the target board layout, as it differs physically from the WLCSP form factor of the original UKAZ component.
