74ALVC164245BX,518

Overview

The 74ALVC164245BX,518 is a 16-bit dual-supply translating transceiver manufactured by Nexperia. It features non-inverting three-state bus-compatible outputs for bidirectional data transmission between A and B ports. The device supports mixed voltage environments, with VCCA(A) operating from 1.5 V to 3.6 V and VCCB(B) from 1.5 V to 5.5 V. It includes direction control inputs (DIR) and output enable inputs (OE). The component offers high impedance outputs when powered down and complies with JEDEC standards for ESD protection.

Feature Summary

• Dual-supply architecture enabling translation between 3 V and 5 V logic levels
• Non-inverting three-state outputs compatible with standard bus systems
• Dedicated direction control and output enable inputs for precise data flow management
• High-impedance state during power-down to prevent backflow current

Applications

• Connecting 3 V and 5 V buses in mixed voltage power environments
• Bidirectional level translation in embedded systems
• Data routing in industrial control modules

Procurement Notes

Verify the specific suffix BX,518 against official Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm end-of-life status as distributor records indicate potential obsolescence. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component for applications requiring robust translation between 3 V and 5 V domains. Verify that the required supply voltage ranges align with system design constraints. Consider the 48-pin TSSOP package dimensions for layout planning. Check if alternative packages are available if space or thermal requirements differ.
