SN74ALVC164245KR: A Versatile Logic Level Translator from Texas Instruments

The SN74ALVC164245KR is a high-performance, 16-bit dual-supply bus transceiver from Texas Instruments designed to address the need for flexible voltage level translation in multi-voltage systems. This device is part of the ALVC (Advanced Low-Voltage CMOS) family, which offers a combination of low static and dynamic power consumption while providing high-speed operation.

With its dual-supply voltage capability, the SN74ALVC164245KR can translate signals between two different logic levels. The A side is designed to operate at 1.65V to 3.6V, while the B side can function at 2.3V to 5.5V, making it ideal for interfacing between low-voltage and high-voltage circuits. This feature is particularly useful in applications where different subsystems operate at different voltage levels, such as mixed-voltage systems in telecommunications, computing, and consumer electronics.

The device features 16-bit bi-directional data flow, with direction control (DIR) and output enable (OE) inputs that simplify the control of data transmission. The DIR input determines the direction of data flow, allowing the device to act as either a transmitter or a receiver. The OE input enables or disables the outputs on the B side, providing additional flexibility in controlling the interface.

One of the key benefits of the SN74ALVC164245KR is its robust design, which includes bushold circuitry on the A-side inputs. This feature eliminates the need for external pull-up or pull-down resistors, saving board space and reducing component count. Additionally, the device is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions.

The SN74ALVC164245KR comes in a 48-pin SSOP (Shrink Small-Outline Package) that is RoHS compliant, minimizing the environmental impact and meeting regulatory requirements for lead-free components. Whether you are designing a new system or upgrading an existing one, the SN74ALVC164245KR provides a reliable and efficient solution for high-speed logic level translation.
