The SNJ54LVTH162245WD is a 16-bit non-inverting transceiver from Texas Instruments, part of the 54LVTH BiCMOS logic family. It operates from 2.7V to 3.6V, optimized for 3.3V systems. Each of the 2 channels can source 24mA and sink 48mA, providing excellent drive capability for high-capacitance buses. The 3-State outputs enable multiple devices to share a common bus. Packaged in a 48-CFlatPack, it is designed for high-density, low-profile applications. With a -55°C to 125°C temperature range, it is suitable for military and aerospace environments.
- High 48mA Sink Current: Drives heavy capacitive loads and long bus traces, ensuring signal integrity in complex systems.
- Low-Voltage 2.7V-3.6V Operation: Compatible with standard 3.3V logic, reducing power consumption compared to 5V parts.
- 16-Bit Wide Bus: Reduces component count by integrating two 8-bit channels in one package.
- 3-State Outputs: Facilitates bus sharing and hot-swap applications without electrical damage.
- Military Temperature Range (-55°C to 125°C): Reliable in extreme environments, ideal for defense and aerospace.
