74AVC4T774BQ-Q100X

Overview

The Nexperia 74AVC4T774BQ-Q100X is a 4-bit dual supply translating transceiver with 3-state outputs, qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 0.8 V to 3.6 V on both ports (VCCA and VCCB). The device supports bidirectional level translation between low-voltage nodes including 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. Maximum data rates reach 380 Mbit/s for translations between 1.8 V and 3.3 V. It features individual direction control inputs (DIRn) and an output enable input (OE), housed in a DHVQFN16 package.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Bidirectional level translation capability across multiple low-voltage logic levels
• Independent per-channel direction control inputs for flexible signal routing
• IOFF circuitry enables partial power-down mode to prevent backflow current

Applications

• Automotive electronic systems requiring robust voltage translation
• Mixed-signal interfaces connecting different voltage domains
• Low-voltage bus systems operating between 0.8 V and 3.6 V
• Partial power-down applications in battery-operated automotive modules

Procurement Notes

Verify the specific suffix Q100X corresponds to the required automotive grade and packaging configuration. Confirm that the DHVQFN16 package variant matches your PCB footprint requirements. Ensure compatibility with AEC-Q100 Grade 1 reliability standards for your target application environment. Check datasheet specifications for thermal dissipation limits under your expected operating conditions.

Selection Notes

Select this component when designing automotive circuits requiring bidirectional translation between varying low-voltage logic levels. The independent DIRn pins allow precise control over data flow direction for each bit. Consider the IOFF feature if the design requires safe operation during partial power-down states. Verify that the 380 Mbit/s maximum data rate meets the speed requirements of your specific interface protocol.

Part Context

This part belongs to the 74AVC4T774-Q100 family of translating transceivers from Nexperia. It is specifically designed for automotive applications, adhering to strict reliability standards. The BQ suffix indicates the DHVQFN16 package type, while the X suffix typically denotes reel packaging. It serves as a bridge between different voltage domains in complex automotive electronic architectures.

Replacement Considerations

The 74AVC4T774GU-Q100 is a confirmed alternative within the same family, utilizing an XQFN16 package instead of DHVQFN16. Designers must verify pinout compatibility and thermal performance differences between the two package types before substitution.
