74LCX38MTC

Inverter Gates Overview

The onsemi 74LCX38MTC is a low-voltage quad 2-input NAND gate featuring open-drain outputs. It utilizes advanced CMOS technology to deliver high-speed performance while maintaining low power consumption. The device supports a supply voltage range of 2.3V to 3.6V and incorporates 5V-tolerant inputs, enabling direct interfacing between 5V and 3V systems. At VCC = 3.3V, the maximum propagation delay is 5.0ns. It offers strong drive capability with an output current of 24mA at VCC = 3.0V and includes proprietary noise/EMI reduction circuits for enhanced signal integrity.

Inverter Gates Feature Summary

• Features 5V tolerant inputs allowing seamless interface between 5V and 3V logic systems
• Provides high-speed operation with low power dissipation through advanced CMOS fabrication
• Delivers strong output drive capability suitable for demanding load conditions
• Incorporates proprietary circuitry designed to reduce noise and electromagnetic interference

Inverter Gates Applications

• Interface bridging between 5V legacy systems and modern 3V logic components
• Open-drain bus applications requiring wired-AND logic configurations
• High-speed digital signal processing circuits in portable electronic devices
• General-purpose logic gating in low-voltage embedded control systems

Inverter Gates Procurement Notes

Verify the specific package variant matches the required footprint, as the MTC suffix denotes a 14-pin TSSOP. Confirm lead-free status if environmental compliance is mandatory, noting that certain ordering codes may include specific packaging suffixes like X or NL. Ensure the selected component aligns with the intended operating temperature range and voltage specifications for the target application design.

Inverter Gates Selection Notes

Select this component when open-drain NAND functionality is required within a low-voltage environment. The 5V tolerance feature makes it ideal for mixed-voltage designs where level shifting is necessary without additional external components. Consider the propagation delay and drive strength requirements to ensure compatibility with the system's timing constraints and load characteristics.

Inverter Gates Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices manufactured by onsemi. The series is characterized by its ability to operate at reduced supply voltages while maintaining compatibility with standard logic levels. The 74LCX38 specifically provides four independent 2-input NAND gates with open-drain outputs, distinguishing it from push-pull variants like the 74LCX00.

Inverter Gates Replacement Considerations

Direct functional substitutes within the same family include the 74LCX38MX_NL and 74LCX38SJ. Verify pinout compatibility and electrical parameters before substitution. Alternative packages such as SOIC (74LCX38M) offer the same logical function but require appropriate PCB layout adjustments.
