SN74GTLPH1645DGGR - Texas Instruments

The SN74GTLPH1645DGGR is a high-performance, 16-bit bus transceiver and voltage translator from Texas Instruments designed for bi-directional communication between data buses. This device is particularly suitable for applications that require high-speed data transfer and voltage translation between different logic levels. It is commonly used in computing, networking, and telecommunication systems where interfacing between different voltage domains is necessary.

Featuring a GTLP (Gunning Transceiver Logic Plus) interface, the SN74GTLPH1645DGGR provides a seamless connection between 3.3V GTLP level signals and 5V TTL or CMOS levels. This makes it an ideal choice for bridging legacy systems with newer technology platforms, ensuring compatibility and extending the life of existing equipment.

The device comes in a 48-pin TSSOP (Thin Shrink Small Outline Package) form factor, designated by the DGGR suffix in its part number, which offers a compact footprint while allowing for efficient thermal dissipation. This package is suitable for surface-mount technology (SMT), which is essential for modern high-density electronic assemblies.

Key features of the SN74GTLPH1645DGGR include:

• 16-bit bidirectional data flow, with individual direction controls for each 8-bit bus.
• Support for mixed-mode signal operation, allowing translation between GTLP levels and TTL/CMOS levels.
• Low on-state resistance, which facilitates low power consumption and minimal signal distortion.
• High-speed data transfer capabilities, ensuring reliable operation in critical applications.
• Bus Hold on data inputs to eliminate the need for external pull-up/pull-down resistors.
• Flow-through pinout to simplify PCB layout.

With its robust design and advanced features, the SN74GTLPH1645DGGR is engineered to meet the stringent requirements of high-speed data communication and translation. Its reliability and versatility make it a preferred choice for system designers looking to maintain signal integrity across different voltage domains and interface standards.
