SN74ALVCHR16601VR Universal Bus Transceiver by Texas Instruments

The SN74ALVCHR16601VR from Texas Instruments is a high-performance, 18-bit universal bus transceiver that operates from a 2.5 V to 3.6 V V_CC. It is designed to provide bidirectional communication between data buses in a variety of applications, including telecommunications, computing, and networking systems.

This robust transceiver features a dual-supply-voltage design, enabling it to interface between a 3.3 V bus and a 2.5 V bus without the need for additional level shifting. The SN74ALVCHR16601VR is part of the ALVC (Advanced Low-Voltage CMOS) family, which is known for its low power consumption and high-speed operation, making it an ideal choice for power-sensitive and high-speed applications.

The device includes 18-bit bus transceivers with 3-state outputs, allowing for direction control and output enable. The direction control (DIR) input determines the direction of data flow: when DIR is high, data flows from the A bus to the B bus, and when DIR is low, the data flows from the B bus to the A bus. The output enable (OE) input, when active, places the outputs in a high-impedance state, allowing for multiple devices to be connected to the same bus line.

The SN74ALVCHR16601VR offers a wide data bandwidth and provides edge-rate control circuitry that significantly reduces signal noise, making it suitable for backplane applications or where signal integrity is critical. The bus-hold circuitry on the device ensures that last active signals are held, preventing floating inputs and reducing system power consumption.

Designed with latch-up performance exceeding 250 mA per JESD 17, and ESD protection exceeding JESD 22, the SN74ALVCHR16601VR ensures reliability and robustness in harsh environments. The device is available in a thin shrink small-outline package (TSSOP), which is optimized for reduced space on printed circuit boards.

With its combination of high-speed operation, low power consumption, and advanced features, the SN74ALVCHR16601VR universal bus transceiver from Texas Instruments is an excellent choice for designers looking to improve the performance and efficiency of their data bus communications.
