NLV14538BDG

Overview

The NLV14538BDG 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 features latched trigger inputs and separate latched reset inputs, allowing for flexible triggering from either the positive edge (A input) or negative-going edge (B input). It is housed in a SOIC-16 package and is AEC-Q100 qualified with PPAP capability.

Feature Summary

• Dual precision monostable multivibrator architecture with independent timing control
• Retriggerable and resettable functionality for extended pulse width generation
• Latched trigger and reset inputs ensuring stable operation under varying signal conditions

Applications

• Timing delay circuits requiring precise pulse width control
• Debouncing switches or contacts in digital logic systems
• Pulse stretching applications for signal synchronization

Procurement Notes

Verify that the specific ordering suffix BDG corresponds to the SOIC-16 package variant as documented in the manufacturer's ordering information. Confirm compliance with automotive qualification standards if the application requires AEC-Q100 certification and PPAP capability. Ensure design specifications align with the maximum ratings provided in the datasheet to prevent device damage.

Selection Notes

Select this component when dual monostable channels are required within a single package footprint. Consider the wide supply voltage range and high-temperature operation capabilities for robust industrial or automotive environments. Evaluate external timing components RX and CX to achieve the desired output pulse width, noting that accuracy depends on these external values.

Part Context

This part belongs to the MC14538B family of dual precision monostable multivibrators. The NLV prefix indicates it meets specific automotive and unique site control change requirements. It is pin-for-pin compatible with other standard monostable multivibrators like the MC14528B and CD4528B, facilitating direct replacements in existing designs.

Replacement Considerations

Pin-for-pin compatible with MC14528B and CD4528B.
