NLV14538BDWR2G

Overview

The NLV14538BDWR2G 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 triggering from either the positive edge (A input) or negative-going edge (B input). Output pulse width is determined by external timing components RX and CX, with a specified range from 10 microseconds to 10 seconds. It is housed in a SOIC-16WB package.

Feature Summary

• Dual precision monostable multivibrator architecture with independent timing networks for each channel
• Retriggerable functionality allows output pulse extension upon valid trigger events during active state
• Resettable design enables immediate termination of the output pulse via dedicated reset inputs
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load

Applications

• Pulse generation circuits requiring precise timing control
• Debouncing switches or contacts in digital logic systems
• Timing delay applications in industrial control environments
• Automotive electronics requiring AEC-Q100 qualified components

Procurement Notes

Verify that the specific ordering suffix matches the required package type and shipping quantity. Confirm PPAP capability requirements if used in automotive assembly lines. Ensure compliance with RoHS directives and lead-free specifications for environmental standards. Check for any site-specific control change notifications associated with the NLV prefix designation before finalizing procurement orders.

Selection Notes

Select this component when dual-channel monostable operation is required with wide pulse width flexibility. Consider the SOIC-16WB package for surface-mount assembly needs. Evaluate external timing component leakage and capacitance limits to ensure accurate pulse generation across the full temperature range. Verify compatibility with existing logic families regarding drive current capabilities and voltage levels.

Part Context

This part belongs to the MC14538B series of dual precision monostable multivibrators. The NLV prefix indicates it meets automotive qualification standards including AEC-Q100 and PPAP capability. It serves as a specialized variant designed for applications requiring unique site and control change requirements compared to standard commercial grade devices.

Replacement Considerations

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