74AVCB164245ZRDR Description

The 74AVCB164245ZRDR from Texas Instruments is a bidirectional voltage-level translator designed for seamless interfacing between mixed-voltage systems. Part of the 74AVCB series, this IC supports voltage translation between 1.4V and 3.6V on both VCCA and VCCB rails, making it ideal for bridging low-voltage logic families like 1.8V, 2.5V, and 3.3V. Packaged in a 54-ball BGA (Tape & Reel), it features two 8-bit channels for bidirectional data flow, ensuring robust signal integrity in high-speed applications. Although marked as Obsolete, it remains relevant for legacy designs due to its REACH Unaffected and ROHS3 Compliant status, alongside a Moisture Sensitivity Level (MSL) of 1 (Unlimited) for extended shelf life.

74AVCB164245ZRDR Features

• Wide Voltage Range: Supports 1.4V to 3.6V on both ports, enabling flexible integration with diverse logic levels.
• Bidirectional Channels: 16-bit (2x8-bit) bidirectional design eliminates the need for separate input/output ICs.
• Low Power Consumption: Optimized for power-sensitive applications with minimal static current draw.
• High-Speed Operation: Suitable for fast data transmission in mixed-voltage systems (e.g., I²C, SPI).
• Robust Packaging: 54-BGA ensures compact footprint and reliable performance in surface-mount applications.
• Compliance: ROHS3 Compliant and REACH Unaffected, meeting stringent environmental standards.

74AVCB164245ZRDR Applications

• Mixed-Voltage Systems: Bridges 1.8V/2.5V/3.3V logic in FPGA, ASIC, or microcontroller interfaces.
• Portable Electronics: Ideal for battery-powered devices (e.g., smartphones, tablets) requiring voltage translation.
• Industrial Automation: Ensures signal compatibility in sensor networks, PLCs, and motor controllers.
• Communications Equipment: Facilitates level shifting in UART, I²C, or SPI buses for embedded systems.
• Legacy Upgrades: Suitable for retrofitting older designs due to its obsolete-but-reliable status.

Conclusion of 74AVCB164245ZRDR

The 74AVCB164245ZRDR offers a versatile, high-performance solution for bidirectional voltage translation, despite its obsolete status. Its wide voltage range, dual-channel design, and compliance with environmental standards make it a pragmatic choice for legacy systems and mixed-voltage applications. While newer alternatives exist, this IC remains valuable for designs prioritizing proven reliability, compact packaging, and low-power operation. Engineers should evaluate replacement options for long-term availability but can leverage this translator for short-run or maintenance projects.
