NL17SZ38DBVT1G

Overview

The NL17SZ38DBVT1G is a single 2-input NAND gate with an open-drain output from the onsemi NL17SZ series. It operates within a supply voltage range of 1.65 V to 5.5 V and supports inputs/outputs overvoltage tolerant up to 5.5 V. The device features IOFF for partial power-down protection and can sink 32 mA at 4.5 V. Typical propagation delay is 2.2 ns at 5 V. It is housed in a SC-74A (SC-70-5) package.

Feature Summary

• Open-drain output configuration suitable for level shifting and wired-AND applications
• IOFF function enables partial power-down protection by limiting leakage current
• Input/output overvoltage tolerance allows interfacing with higher voltage systems

Applications

• Level translation between different voltage domains
• Wired-logic bus configurations requiring open-drain outputs
• General-purpose digital logic processing in portable devices

Procurement Notes

Verify the specific ordering suffix DBVT1G corresponds to the SC-74A package and tape & reel shipping format. Confirm RoHS compliance and Pb-free status as indicated in the datasheet. Ensure the application circuit accounts for the open-drain nature of the output, which requires an external pull-up resistor for proper high-state operation.

Selection Notes

Select this component when a compact 2-input NAND gate with open-drain capability is required. It is suitable for designs needing input overvoltage tolerance beyond the supply rail. Consider the SC-74A package size constraints and the necessity of an external pull-up resistor for the output stage compared to standard push-pull logic gates.

Part Context

This part belongs to the NL17SZ family of low-voltage CMOS logic devices manufactured by onsemi. The family focuses on small form-factor packages and wide operating voltage ranges. The NL17SZ38 specifically provides NAND functionality with an open-drain output, distinguishing it from standard push-pull variants like the NL17SZ08.
