SN74HSTL16919DGGR by Texas Instruments

The SN74HSTL16919DGGR is a high-speed, low-voltage 18-bit universal bus transceiver with 3-state outputs. Engineered by the renowned semiconductor manufacturer Texas Instruments, this product is designed to deliver exceptional performance for the latest generation of communication and computing applications. It is a part of the HSTL (High-Speed Transceiver Logic) family, which is known for its reduced power consumption and high-speed operation.

This transceiver operates from a 3.3V supply, making it compatible with low-voltage systems, and it can support signaling rates up to several hundred megabits per second. The SN74HSTL16919DGGR features 18 data input-output ports, which can be used bidirectionally, providing flexibility and ease of use for various data bus configurations.

One of the key features of this device is its bus-hold data inputs, which eliminate the need for external pull-up resistors and ensure that the inputs remain at a valid logic level even when they are not actively being driven. The device's use of edge-rate control circuitry minimizes the noise generated by high-speed data transitions, contributing to signal integrity and reducing the likelihood of data errors.

The SN74HSTL16919DGGR is housed in a slim TSSOP (Thin Shrink Small Outline Package) with 56 pins, identified by its DGGR suffix. This package is designed for space-saving on PCBs (Printed Circuit Boards) and is suitable for automated surface-mount assembly processes. The product is also characterized for operation from -40°C to 85°C, making it reliable in a wide range of environmental conditions.

Applications for the SN74HSTL16919DGGR are varied and include high-speed data transfer systems, such as backplane interconnects, and communication infrastructure equipment. It is also commonly used in servers, routers, and other equipment where efficient and reliable data transmission is critical.

Texas Instruments provides comprehensive technical support for the SN74HSTL16919DGGR, including detailed datasheets, application notes, and design resources, ensuring that engineers can integrate this transceiver into their designs with confidence and efficiency.
