NL17SZ14DBVT1G

Overview

The NL17SZ14DBVT1G is a single-channel Schmitt trigger inverter manufactured by onsemi, belonging to the 17SZ logic series. It operates within a supply voltage range of 1.65V to 5.5V and features low static current consumption of 1 µA maximum. The device provides robust output drive capabilities with high and low level output currents of 32mA each. It exhibits a maximum propagation delay of 5.9ns at 5V with a 50pF load. Designed for surface mount applications, it utilizes an SC-74A (SOT-23-5) package and supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Integrates Schmitt trigger input characteristics to ensure clean signal transitions and noise immunity.
• Delivers strong 32mA output drive capability suitable for driving capacitive loads and transmission lines.
• Operates across a wide supply voltage range from 1.65V to 5.5V for flexible system integration.

Applications

• Signal conditioning and waveform shaping in digital circuits
• Noise filtering for inputs subject to slow rise or fall times
• Level shifting between different voltage domains

Procurement Notes

Verify the specific ordering suffix DBVT1G to confirm the SC-74A package and tape-and-reel quantity. Confirm RoHS compliance status and manufacturing origin details against the latest datasheet revision. Check for any recent PCN notifications regarding assembly location or material changes that may affect qualification. Ensure the component matches the required lead-free specifications for your assembly process.

Selection Notes

Select this component when Schmitt trigger hysteresis is required for a single inverter function in space-constrained designs. The SC-74A package offers a compact footprint compared to standard SOT-23 variants. Consider the 1.65V minimum supply voltage if interfacing with low-voltage logic families. Verify that the 5.9ns propagation delay meets the timing requirements of the target application.

Part Context

This part belongs to the onsemi 17SZ series of ultra-low voltage CMOS logic devices. The series focuses on providing high performance with minimal power consumption in small packages. The NL17SZ14 specifically implements the inverter function with added Schmitt trigger inputs, distinguishing it from standard inverters like the NL17SZ04 which lack hysteresis.

FAQ

What is the purpose of the Schmitt trigger feature in this inverter?

The Schmitt trigger input provides hysteresis, which prevents output oscillation caused by noise or slow-moving input signals, ensuring stable switching behavior.

Does the DBVT1G suffix indicate a change in logical function?

No, the suffix indicates the packaging type (SC-74A) and reel configuration; the logical function remains a single Schmitt trigger inverter.
