Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and green manufacturing status. Ensure the A variant designation matches specific design requirements regarding propagation delay or package tolerance. Confirm the TSSOP-20 footprint aligns with PCB layout specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between TTL-driven controllers and CMOS-based peripheral buses. The HCT series ensures robust noise immunity at 5V operation. Consider the A suffix if tighter performance tolerances are required compared to standard variants. Evaluate thermal dissipation needs given the dense TSSOP-20 packaging constraints.
