NLV14043BDG

Latches Overview

The NLV14043BDG is a CMOS MSI Quad R-S Latch manufactured by onsemi. It features four independent latches with Set and Reset inputs, providing individual Q outputs gated through three-state buffers controlled by a common Enable input. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an ambient temperature range from -55°C to +125°C. It is housed in a SOIC-16 package (Case 751B) and includes double diode input protection.

Latches Feature Summary

• Triple-state outputs with a common enable input for bus driving applications
• Double diode input protection against high static voltages or electric fields
• AEC-Q100 qualified and PPAP capable for automotive requirements

Latches Applications

• Automotive electronic systems requiring unique site and control change requirements
• General-purpose data storage and buffering circuits
• Bus-oriented memory applications utilizing three-state output capability

Latches Procurement Notes

Verify the specific ordering suffix 'NLV' indicates AEC-Q100 qualification and PPAP capability as required for automotive applications. Confirm the package type is SOIC-16 and that the component is lead-free and RoHS compliant. Ensure the procurement channel provides official datasheets matching publication number MC14043B/D for accurate electrical parameter validation.

Latches Selection Notes

Select this component when a quad latch with three-state output control is needed for automotive environments. The NLV prefix specifically denotes compliance with automotive quality standards including AEC-Q100 and PPAP. Compare against standard MC14043B if automotive qualification is not required. Ensure the design accommodates the specified operating temperature range and supply voltage limits.

Latches Part Context

This part belongs to the MC14043B/44B family of CMOS MSI logic devices. The NLV prefix distinguishes it as the automotive-grade variant, ensuring specific manufacturing site controls and change management protocols. It serves as a fundamental building block for sequential logic in harsh environments where standard commercial grade parts may not suffice.

Latches Replacement Considerations

MC14043BDG is the commercial equivalent without automotive qualification. MC14044BDG offers inverted Set/Reset logic functionality within the same package and specifications.
