NLVHC4538ADR2G

Overview

The NLVHC4538ADR2G is a dual precision monostable multivibrator manufactured by onsemi. It operates within a supply voltage range of 3.0 V to 6.0 V and supports surface-mount installation in an SOIC-16 package. The device features retriggerable and resettable functionality, allowing for precise output pulse generation determined by external timing components. It is designed with high noise immunity and low input current characteristics typical of CMOS logic families.

Feature Summary

• Dual precision monostable multivibrator architecture providing two independent timing channels
• Retriggerable and resettable operation capabilities for flexible signal conditioning
• High noise immunity and low power consumption suitable for sensitive electronic environments

Applications

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

Procurement Notes

Verify the specific suffix 'ADR2G' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compliance with AEC-Q100 automotive qualification requirements if deploying in vehicle electronics. Confirm RoHS and halogen-free status through the manufacturer's latest product change notifications before procurement.

Selection Notes

Select this component when a dual-channel precision timer is required within standard CMOS voltage limits. Consider the SOIC-16 footprint for PCB layout constraints. Evaluate the need for retriggerability versus simple one-shot triggering to determine if this specific variant meets the system's timing stability requirements compared to non-retriggerable alternatives.

Part Context

This part belongs to the HC4538 family of dual precision monostable multivibrators. It shares functional compatibility with legacy MC14538B designs while offering modern manufacturing standards. The NLV prefix indicates automotive-grade qualification, aligning it with other onsemi solutions for harsh environment applications requiring robust performance and traceability.

Replacement Considerations

Direct pin-compatible substitutes include the MC74HC4538ADTR2G and MC14538BDWR2G. Verify electrical parameter equivalence and package dimensions before substitution. Note that generic equivalents may lack the specific automotive qualification associated with the NLV prefix.
