SN74ALVCH16825DLR 18-Bit Universal Bus Driver with 3-State Outputs

The SN74ALVCH16825DLR from Texas Instruments is a high-performance, 18-bit universal bus driver designed to facilitate bus-oriented applications. This device is part of the ALVCH series, which is known for its low-voltage operation and high-speed interface technology. The SN74ALVCH16825DLR is particularly suitable for those applications that require a high-speed, low-power bus interface with a 3-state output feature for bus-oriented applications.

With a wide bus-interface capability, the SN74ALVCH16825DLR can operate at 2.5V to 3.6V, making it versatile for interfacing with different logic levels. The device supports a significant data bandwidth, which makes it an ideal choice for high-speed data transfer and communication systems. The 3-state outputs ensure that multiple devices can share a common bus without interference, as the outputs can be placed in a high-impedance state.

The SN74ALVCH16825DLR features 18-bit inputs and outputs, organized as two 9-bit bus transceivers with 3-state outputs. The device allows data flow from A to B or B to A, depending upon the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

One of the key benefits of the SN74ALVCH16825DLR is its support for low-voltage operation and low static power consumption, which is critical in battery-powered and power-sensitive applications. Additionally, the device offers a bus-hold feature that retains the last active state when no input signal is present, reducing the need for external pull-up or pull-down resistors.

Furthermore, the SN74ALVCH16825DLR is packaged in a 56-pin SSOP (Shrink Small Outline Package) which is ideal for space-constrained applications. This product is characterized for operation from -40°C to 85°C, making it reliable in a wide range of environmental conditions.

Overall, the SN74ALVCH16825DLR is a robust, high-speed bus driver that provides a reliable interface solution for data-intensive applications. Its low-power consumption and versatile features make it an excellent choice for designers looking to optimize their system performance while maintaining power efficiency.
