74AVC4T774GUX

Overview

The Nexperia 74AVC4T774GUX is a 4-bit dual supply translating transceiver housed in an XQFN16 package (SOT1161-1). It supports bidirectional level translation between voltage nodes ranging from 0.8 V to 3.6 V on both VCC(A) and VCC(B). The device features four independent direction control inputs (DIRn) and an active LOW output enable input (OE). It complies with JEDEC standards for various low-voltage ranges, offers maximum data rates up to 380 Mbit/s, and includes IOFF circuitry for partial power-down applications.

Feature Summary

• Bidirectional level translation between any low voltage nodes within the 0.8 V to 3.6 V range
• Independent direction control for each of the four channels via DIRn inputs
• IOFF circuitry prevents damaging backflow current during partial power-down states
• High ESD protection exceeding 8000 V (HBM) and 1500 V (CDM)

Applications

• Interfacing between different low voltage digital logic nodes
• Partial power-down mode operation in multi-supply systems
• Bidirectional bus translation in portable electronic devices

Procurement Notes

Verify that the ordering suffix 'GUX' corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm the XQFN16 package dimensions match your PCB footprint design. Ensure the component meets the required temperature range specifications for your intended operating environment before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring independent direction control for each bit of a 4-bit bus. It is suitable for applications needing translation between widely varying low voltages, such as 1.2 V to 3.3 V. Consider the XQFN16 package size constraints and thermal dissipation requirements relative to the total power dissipation limits specified in the datasheet.

Part Context

This part belongs to the 74AVC logic family, which utilizes Advanced Very-low-voltage CMOS technology. It is designed for high-speed applications requiring low power consumption. The 74AVC4T774 variant specifically provides four bits of translation with individual direction control, distinguishing it from simpler auto-direction sensing translators or fixed-direction buffers.

Replacement Considerations

Check for other variants within the 74AVC4T774 series, such as those in the DHVQFN16 package, if the XQFN16 form factor is not strictly mandatory. Verify pin compatibility and electrical characteristics against alternative translating transceivers from the same manufacturer or other vendors offering similar 4-bit bi-directional level shifters.
