74VCX38M

Inverter Gates Overview

The Fairchild Semiconductor 74VCX38M is a high-speed CMOS logic device containing four independent 2-input NAND gates. It features open-drain outputs, making it suitable for interfacing with various logic families and bus structures. The component operates within a low voltage supply range of 1.2V to 3.6V. It utilizes a 14-pin SOIC package (JEDEC MS-012AA). Key electrical characteristics include a maximum quiescent current of 20 µA and a typical propagation delay of 2.8 ns at the specified operating voltage.

Inverter Gates Feature Summary

• Contains four independent 2-input NAND gates
• Features open-drain output configuration
• Operates on low voltage supplies from 1.2V to 3.6V

Inverter Gates Applications

• Low-voltage digital logic circuits
• Bus interface applications requiring level shifting
• Open-drain pull-up configurations

Inverter Gates Procurement Notes

Verify the specific suffix or tape-and-reel designation if continuous manufacturing supply is required, as packaging formats may vary. Confirm RoHS compliance status for the specific batch, as older stock may differ from current production runs. Ensure the 14-SOIC package width matches the PCB footprint requirements before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when designing systems that require multiple NAND functions in a single package under low voltage constraints. The open-drain output allows for wired-AND connections and flexible voltage translation between different logic domains. Consider the 2.8 ns propagation delay for timing-critical paths within the 1.2V to 3.6V operational window.

Inverter Gates Part Context

This part belongs to the VCX series of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. The series is designed for portable and battery-operated applications where power consumption is critical. The 74VCX38M specifically provides basic NAND functionality with the added flexibility of open-drain outputs, distinguishing it from standard push-pull logic gates in the same family.

Inverter Gates Replacement Considerations

Direct pin-compatible substitutes may include other 74VCX38 variants from different manufacturers offering identical 14-SOIC footprints and logical functionality. Verify that any replacement maintains the 1.2V to 3.6V supply range and open-drain output specifications to ensure circuit compatibility.
