TC74HC03AP

Inverter Gates Overview

The TC74HC03AP is a CMOS digital integrated circuit manufactured by Toshiba Semiconductor and Storage. It contains four independent 2-input NAND gates with open-drain outputs, housed in a 14-DIP package. The device operates within a supply voltage range of 2V to 6V. Key electrical parameters include a maximum quiescent current of 1 µA, output currents of 5.2mA for both high and low states, and a maximum propagation delay of 13ns at 6V with 50pF load capacitance. Input logic levels are defined as 0.5V to 1.8V for low and 1.5V to 4.2V for high.

Inverter Gates Feature Summary

• Features four independent 2-input NAND logic functions within a single package.
• Provides open-drain output configuration suitable for wired-AND applications or level shifting.
• Operates across a wide supply voltage range from 2V to 6V.
• Maintains low static power consumption with a maximum quiescent current of 1 µA.

Inverter Gates Applications

• General-purpose digital logic processing
• Wired-AND bus configurations
• Level translation interfaces
• Microcontroller peripheral interfacing

Inverter Gates Procurement Notes

Verify the specific suffix 'AP' confirms the 14-DIP through-hole package variant. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the open-drain output characteristic aligns with your circuit design requirements, as pull-up resistors may be necessary for proper logic high levels. Cross-reference the manufacturer part number TC74HC03AP against official Toshiba documentation to validate availability and lead times.

Inverter Gates Selection Notes

Select this component when a quad 2-input NAND gate with open-drain outputs is required. The HC series offers compatibility with standard 5V logic systems while supporting lower voltages down to 2V. Consider the 14-DIP package for prototyping or through-hole manufacturing. Verify that the 5.2mA drive capability meets the load requirements of your downstream components.

Inverter Gates Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. The base product number is 74HC03. It is distinct from the TC74HC00, which provides standard push-pull outputs rather than open-drain. The TC74HC03AP is designed for general digital applications requiring reliable NAND logic functionality with flexible output driving capabilities.

Inverter Gates Replacement Considerations

The TC74HC00AP serves as a functional substitute if open-drain outputs are not required, offering standard push-pull outputs instead. Other 74HC03 variants from different manufacturers may be compatible provided pinouts and electrical specifications match. Verify package dimensions and thermal characteristics before substituting.
