74LCX38SJ

Inverter Gates Overview

The Fairchild Semiconductor 74LCX38SJ is a low-voltage quad 2-input NAND gate featuring open-drain outputs. It operates within a supply voltage range of 2V to 3.6V and supports inputs tolerating up to 7V, enabling interface between 5V systems and 3V logic. The device is housed in a 14-SOP package with a maximum propagation delay of 5ns at 3.3V with 50pF load.

Inverter Gates Feature Summary

• Provides four independent 2-input NAND logic functions
• Features open-drain output configuration for flexible interfacing
• Supports 7V input tolerance for mixed-voltage system compatibility

Inverter Gates Applications

• Interface bridging between 5V and 3V logic domains
• Low-voltage digital signal processing circuits
• General-purpose logic gating in portable electronic devices

Inverter Gates Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the 14-SOP package matches your PCB footprint requirements. Ensure design specifications accommodate the open-drain output nature, which requires external pull-up resistors for proper high-state operation. Check for RoHS compliance documentation if required by your manufacturing standards.

Inverter Gates Selection Notes

Select this component when designing low-voltage logic circuits requiring NAND functionality with mixed-voltage input tolerance. The open-drain output allows for wired-AND configurations or level shifting. Consider the 5ns propagation delay for timing-critical applications operating at 3.3V. Verify that the 14-SOP package size fits within the available board space constraints.

Inverter Gates Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. The LCX family is designed for high-speed operation with low power consumption, suitable for battery-powered applications. The 74LCX38 specifically implements NAND logic with open-drain outputs, distinguishing it from standard push-pull logic families.
