STMicroelectronics 74ALVCR162245TTR Transceiver Overview

The 74ALVCR162245TTR from STMicroelectronics is a high-speed, low-voltage CMOS 16-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs. It is designed for asynchronous communication between data buses and targets applications requiring voltage level shifting capabilities between different logic levels. The device operates with two separate power supply voltages, allowing for translation between 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic levels.

Key Features

• High-Speed Operation: This transceiver is capable of handling fast data transfer rates, making it suitable for high-speed data bus applications.
• Dual-Supply Voltages: It supports dual-supply voltage operation, which allows for interfacing between different logic levels without the need for additional level-shifting components.
• Low Power Dissipation: Its CMOS technology ensures low power dissipation, which is critical for power-sensitive designs.
• Wide Voltage Range: The device can translate signals between a wide range of voltages, from 1.2V to 5V, providing flexibility in mixed-voltage systems.
• Bus Hold Data Inputs: The inputs have a bus hold feature that eliminates the need for external pull-up or pull-down resistors.
• 3-State Outputs: The 3-state outputs ensure that the device can be connected to a data bus as a passive receiver without affecting the bus line.
