The SN74ALVCH16500DGGR is a high-performance, 18-bit universal bus transceiver from Texas Instruments, designed to address the needs of high-speed bidirectional communication in data bus and memory interface applications. This integrated circuit is part of the advanced high-speed CMOS family (ALVCH) and is fabricated with silicon gate CMOS technology to achieve significant power savings and speed enhancements over its predecessors.

Featuring a dual-supply voltage range of 2.3V to 3.6V, the SN74ALVCH16500DGGR ensures compatibility with lower voltage systems while maintaining the ability to interface with standard 5V components. This level of versatility makes it suitable for mixed-voltage environments, providing system designers with a flexible solution for various interfacing challenges.

Key Features:

• High-Speed Operation: The device operates at a high speed, with a typical t<sub>pd of 3.8 ns (max) for 3.3 V, allowing for efficient data transfer between buses.
• Low Power Consumption: It is designed for low static and dynamic power consumption, contributing to overall energy efficiency in electronic systems.
• Wide Bus Interface: The 18-bit bus interface width provides a broad pathway for data, making it ideal for handling large volumes of parallel data.
• Bus-Hold Data Inputs: The device's inputs feature a bus-hold circuitry that retains the last active state when no input signal is present, reducing the need for external pull-up/pull-down resistors.
• Flow-Through Architecture: Its flow-through pinout architecture simplifies PCB layout by facilitating direct connection to buses.
• Output Drive Capability: The transceiver can drive up ±24 mA at the outputs, ensuring strong signal integrity even in capacitive load conditions.

The SN74ALVCH16500DGGR comes in a 48-pin TSSOP (DGGR) package, offering a compact footprint while providing the necessary I/O for complex digital systems. With its robust design and advanced features, this transceiver is well-suited for a wide range of applications, including telecommunications, computing, and industrial systems where reliable high-speed data transmission is crucial.
