SN74ALVC164245DGGT Description

The SN74ALVC164245DGGT from Texas Instruments is a high-performance, dual-supply bidirectional voltage-level translator designed for seamless interfacing between mixed-voltage systems. Housed in a compact 48-pin TSSOP package, this IC supports 8 channels per circuit (2 circuits total) with bidirectional data flow, making it ideal for bridging logic levels between 2.3V–3.6V (VCCA) and 3V–5.5V (VCCB) domains. Its 74ALVC series architecture ensures low-power operation, high-speed signal integrity, and robust noise immunity, meeting stringent industry standards like ROHS3 and REACH compliance.

SN74ALVC164245DGGT Features

• Wide Voltage Range: Supports asymmetric voltage translation (2.3V–3.6V to 3V–5.5V), enabling compatibility with diverse logic families (e.g., 3.3V MCUs to 5V peripherals).
• Bidirectional Channels: Eliminates the need for separate unidirectional translators, reducing board space and BOM complexity.
• High-Speed Operation: Optimized for low propagation delay and minimal skew, critical for high-frequency data buses (e.g., SPI, I2C).
• Robust Packaging: Tape & Reel (TR) delivery and MSL1 (Unlimited) moisture sensitivity ensure reliability in automated assembly processes.
• Low Power Consumption: Advanced ALVC technology minimizes static and dynamic power dissipation, suitable for battery-powered devices.

SN74ALVC164245DGGT Applications

• Mixed-Voltage Systems: Ideal for interfacing 3.3V processors with 5V sensors, memory, or legacy peripherals in industrial automation.
• Communication Modules: Enables level shifting in UART, CAN, or USB-to-Serial converters where bidirectional data flow is essential.
• Portable Electronics: Power-efficient design suits handheld devices, IoT nodes, and wearables requiring voltage adaptation.
• Automotive Electronics: Withstands noisy environments, making it suitable for infotainment systems and ECU communication.
