NLV14538BDR2G

Overview

The NLV14538BDR2G is a dual precision retriggerable and resettable monostable multivibrator manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an operating temperature range from -55°C to +125°C. The device generates accurate output pulses determined by external timing components, with a pulse width range spanning from 10 nanoseconds to 10 seconds. It features latched trigger inputs and separate latched reset inputs, allowing triggering from either the positive edge (A input) or negative-going edge (B input).

Feature Summary

• Dual precision monostable multivibrator architecture supporting both retriggerable and resettable operations.
• Capable of accepting triggers from either the rising edge at the A input or the falling edge at the B input.
• Includes latched trigger inputs and separate latched reset inputs for precise control over timing cycles.
• NLV prefix indicates qualification for automotive applications, meeting AEC-Q100 standards and PPAP capability requirements.

Applications

• Automotive electronic systems requiring unique site and control change requirements.
• Timing circuits generating precise pulse widths using external RC networks.
• Pulse stretching and timing delay applications in industrial logic systems.

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the NLV14538BDR2G designation corresponds to the SOIC-16 tape and reel configuration. Confirm compliance with AEC-Q100 qualification and PPAP capability if the application demands automotive-grade reliability standards. Ensure external timing component values are selected to maintain operation within the specified electrical limits and temperature ranges defined in the datasheet.

Selection Notes

Select this component when a dual-channel monostable solution with retriggering capabilities is required for robust timing applications. The device offers flexibility in trigger edge selection via dedicated A and B inputs. Consider the wide supply voltage range and extended temperature specifications for harsh environments. Verify that the SOIC-16 package format aligns with the PCB layout constraints and assembly processes of the target design.

Part Context

This part belongs to the MC14538B family of dual precision monostable multivibrators. The NLV prefix specifically denotes parts manufactured under strict automotive quality controls, including AEC-Q100 qualification and PPAP capability. These devices serve as alternatives to standard commercial logic timers, providing enhanced reliability for critical system functions where consistent timing performance across varying temperatures is essential.

Replacement Considerations

Pin-for-pin compatible with MC14528B and CD4528B (CD4098). For applications requiring pulse widths less than 10 nanoseconds with supplies up to 6 V, consider the MC54/74HC4538A instead.
