Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and specific package variant. Confirm the TSSOP-48 package type matches the target PCB footprint. Ensure the supply voltage provided to the circuit falls strictly between 2.7 V and 3.6 V to maintain valid logic operation. Check that the application environment remains within the -40°C to +85°C operating temperature range specified for this component.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide bus interface is required with LVTTL compatibility. The LVTH series offers higher drive strength compared to standard LVC devices, making it suitable for driving larger capacitive loads on the bus. The 2.8 ns propagation delay supports moderate to high-speed data transfers. Ensure the system design accommodates the 48-pin TSSOP package dimensions and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVTH162245 family of 3.3-V ABT (Advanced BiCMOS Technology) bus transceivers. It is designed for applications requiring robust performance at 3.3 V supplies. The LVTH series typically provides improved noise immunity and drive capability over previous generations.
