74AVC4T774GUZ

Overview

The Nexperia 74AVC4T774GUZ is a 4-bit dual supply translating transceiver housed in an XQFN16 (SOT1161-1) package. 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 (OE). It complies with JEDEC standards for low-voltage operation, 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 per-channel direction control via DIRn inputs
• IOFF circuitry prevents damaging backflow current during partial power-down
• High ESD protection exceeding 8000 V HBM and 1500 V CDM

Applications

• Interfacing between different low voltage logic nodes
• Partial power-down mode systems requiring isolation
• High-speed data bus translation applications

Procurement Notes

Verify the specific ordering suffix GUZ corresponds to the XQFN16 package variant SOT1161-1. Confirm that the required temperature range covers -40 °C to +125 °C. Ensure the application design accounts for the 250 mW total power dissipation limit associated with this specific package type. Cross-reference the marking code B77 for physical identification.

Selection Notes

Select this component when individual channel direction control is required rather than global auto-direction sensing. It is suitable for designs needing simultaneous translation across widely varying voltage pairs within the specified limits. Consider the XQFN16 package dimensions if board space is constrained compared to leaded alternatives.

Part Context

This part belongs to the 74AVC series of advanced very-low-voltage CMOS logic devices. It functions as a translating transceiver distinct from standard buffers or latches. The GUZ suffix denotes the specific plastic extremely thin quad flat package configuration manufactured by Nexperia USA Inc.

Replacement Considerations

The 74AVC4T774BQ serves as a pin-compatible alternative utilizing the DHVQFN16 package.
