Product Overview: Texas Instruments 74ALVC164245DGGRE4

The Texas Instruments 74ALVC164245DGGRE4 is a high-performance, 16-bit dual-supply bus transceiver designed with two data flow directions. This integrated circuit is part of the ALVC family, which is characterized by its low-voltage operation and high-speed interface technology. The device is particularly suitable for asynchronous communication between two buses of different voltage domains.

Key Features

• Voltage Level Translation: The 74ALVC164245DGGRE4 is capable of translating signals between two different voltage domains, ranging from 1.65V to 3.6V on the A side and 2.3V to 5.5V on the B side. This makes it ideal for interfacing between low-voltage microprocessors and standard 5V TTL/CMOS logic levels.
• High-Speed Operation: With a maximum data rate of 380 Mbps (190 MHz), this transceiver is suitable for high-speed signal transmission, ensuring minimal propagation delay and efficient data handling in critical applications.
• Bus Hold Function: The device includes a bus hold feature on the data inputs, which eliminates the need for external pull-up or pull-down resistors and helps to maintain last active states if the data input becomes disconnected.
• Low Power Consumption: The 74ALVC164245DGGRE4 has been optimized for low power consumption, making it an energy-efficient choice for battery-powered and power-sensitive applications.
• Robust ESD Protection: Enhanced electrostatic discharge (ESD) protection is provided on all pins to prevent damage from static electricity and improve the longevity of the device.

Applications

The versatility of the 74ALVC164245DGGRE4 makes it suitable for a wide range of applications, including:
