74LCX38MTCX

Inverter Gates Overview

The 74LCX38MTCX is a low-voltage quad 2-input NAND gate with open-drain outputs, manufactured by onsemi using advanced CMOS technology. It operates within a supply voltage range of 2.3V to 3.6V and features inputs tolerant up to 7V, enabling interface between 5V and 3V systems. The device offers high-speed performance with a maximum propagation delay of 5.0ns at VCC=3.3V and maintains low power consumption with a maximum static current of 10μA. It provides strong drive capability with an output current of 24mA at VCC=3.0V and includes proprietary noise/EMI reduction circuits for enhanced reliability.

• Incorporates proprietary noise and EMI reduction circuits to improve signal integrity
• Maintains high impedance input and output states during power-off conditions

Inverter Gates Applications

• Interface connections between 5V and 3V logic systems
• Wired-AND logic implementations requiring open-drain outputs
• Level translation circuits in mixed-voltage digital designs
• General-purpose logic control in consumer electronics and industrial equipment

Inverter Gates Procurement Notes

Verify the specific package variant when ordering, as the base part number may correspond to multiple physical packages such as TSSOP or SOIC. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region. Ensure the selected suffix matches the required tape-and-reel or cut-tape packaging format for surface-mount assembly processes.

Inverter Gates Selection Notes

Select this component when open-drain NAND functionality is required for low-voltage applications. The 7V input tolerance makes it suitable for bridging 5V and 3.3V domains without additional level shifters. Consider the 24mA drive strength for driving moderate loads and verify that the open-drain topology aligns with the system's pull-up requirements and timing constraints.

Inverter Gates Part Context

This device belongs to the 74LCX series of low-voltage CMOS logic gates produced by onsemi. The LCX family is designed for high-speed operation while maintaining low power dissipation, making it ideal for battery-powered and portable electronic devices. The 74LCX38 specifically provides quad 2-input NAND gates with open-drain outputs, distinguishing it from standard push-pull variants like the 74LCX00.

Inverter Gates Replacement Considerations

Direct substitutes include other 74LCX38 variants from different manufacturers or package styles, such as the 74LCX38M or 74LCX38SJ. Verify pin compatibility and electrical specifications before substitution. Alternative open-drain NAND gates from the 74LVC or 74HC families may be considered if voltage levels and speed requirements differ.
