Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm status and packaging details. The 'NS' suffix indicates a standard SOP package, which may have different availability or lifecycle status compared to other variants like DW or PW. Confirm RoHS compliance and lead finish specifications directly from the latest datasheet revision before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide voltage compatibility between 2 V and 5.5 V. The LV series offers lower drive strength and slower edge rates compared to AC or ABT families, which helps minimize output ringing in bus interface applications. Ensure input voltages do not exceed 5.5 V even if VCC is lower, as inputs are overvoltage tolerant up to that limit.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV374A family of octal edge-triggered D-type flip-flops. It is designed for high-speed digital logic applications where buffer registers, I/O ports, and bi-directional bus drivers are needed. The device utilizes CMOS technology and is suitable for implementing working registers in systems with varying logic levels.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check the Package Option Addendum for equivalent parts with different statuses such as NRND or Obsolete. Variants like SN74LV374ADBR or SN74LV374APWR offer alternative packages but maintain similar electrical characteristics. Verify pinout compatibility and thermal resistance values when substituting.
