NL17SZ14P5T5G-L22088

Overview

The NL17SZ14P5T5G is a single inverter with Schmitt trigger from the 17SZ series, manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and features input/output overvoltage tolerance up to 5.5 V. The device supports partial power down protection via IOFF and provides source/sink currents of 24 mA at 3.0 V. It is housed in an SOT-953 package (Case 527AE) with five pins. Typical propagation delay is 3.7 ns at 5 V, while maximum quiescent current is 1 µA.

Feature Summary

• Single inverter configuration with Schmitt trigger input for noise immunity
• Supports partial power down protection through IOFF functionality
• Input and output overvoltage tolerant up to 5.5 V regardless of supply voltage
• Available in compact SOT-953 surface-mount package

Applications

• Signal conditioning in low-voltage digital systems
• Noise filtering for logic inputs requiring hysteresis
• Level shifting interfaces between different voltage domains
• Buffering signals in portable battery-powered devices

Procurement Notes

Verify that the ordering suffix P5T5G corresponds specifically to the SOT-953 package variant when sourcing. Confirm RoHS compliance and lead-free status as indicated by the G suffix in standard part numbers. Ensure the supplier provides documentation confirming the specific pin orientation for the SOT-953 case, as it differs from other packages in the family. Check for any automotive-specific variants if AEC-Q100 qualification is required for the application environment.

Selection Notes

Select this component when a single-channel inverter with Schmitt trigger action is needed in a minimal footprint. The SOT-953 package offers a smaller profile compared to SC-88A or SOT-553 options. Consider the 17SZ series characteristics for compatibility with existing LVC/LCX/Z family designs. Evaluate the 24 mA drive capability against load requirements to ensure sufficient output strength for the intended circuit loads.

Part Context

This device belongs to the NL17SZ14 family of single inverters with Schmitt triggers. Other package options include SC-88A (DFT), SC-74A (DBV), and SOT-553 (XV5). The P5T5G suffix denotes the SOT-953 package type. The family shares common electrical characteristics but varies in physical dimensions and pin configurations. This specific variant is designed for applications requiring the smallest available package size within the series.

FAQ

What is the function of the NC pin in the SOT-953 package?

Pin 3 is designated as No Connect (NC) in the SOT-953 package. It is internally unconnected and should not be tied to any voltage or ground potential in the circuit design.

How does the Schmitt trigger feature benefit this inverter?

The Schmitt trigger input provides hysteresis, which prevents multiple output transitions caused by slow-rising input signals or noise. This ensures clean switching even with noisy input waveforms.

Can this device tolerate input voltages higher than its supply voltage?

Yes, the NL17SZ14P5T5G features input/output overvoltage tolerance up to 5.5 V, allowing it to interface with higher voltage logic levels even when operating at lower supply voltages within its 1.65 V to 5.5 V range.
