The SN74AVC1T45YZTR is a highly integrated single-bit dual supply voltage level translator designed by Texas Instruments. This integrated circuit (IC) is part of the AVCxT family and offers voltage translation from a lower voltage to a higher voltage and vice versa. It is specifically designed to work within the voltage range of 1.2V to 3.6V, making it suitable for various applications.
Key Features:
1. Voltage-Level Translation: The SN74AVC1T45YZTR is capable of bidirectional voltage translation between two different supply voltages. This feature allows seamless communication between devices operating at different voltage levels.
2. Dual-Supply Support: This level translator is designed to work with two separate power supplies. The VCCA pin provides the device with the lower voltage supply (1.2V to 3.6V), while the VCCB pin allows for a higher voltage supply (1.65V to 5.5V). This flexibility makes it ideal for interfacing devices with different power requirements.
3. Auto-direction Sensing: The IC incorporates auto-direction sensing circuits that can detect the direction of data flow. This feature eliminates the need for a direction-control signal, simplifying the interface design and reducing pin requirements.
4. Supports Bidirectional Data Transfer: The SN74AVC1T45YZTR supports bidirectional data transfer, enabling seamless communication between two sides of the translator
