MM74HC03N

Inverter Gates Overview

The MM74HC03N is a quad 2-input open-drain NAND gate manufactured by National Semiconductor. It utilizes advanced silicon-gate CMOS technology to achieve high-speed operation with low power consumption. The device operates within a supply voltage range of 4.5V to 5.5V, featuring a maximum quiescent current of 2 µA. Output drive capabilities include 4mA for both high and low states, with an input logic low level threshold of 0.8V. Packaged in a 14-pin PDIP format, it supports operating temperatures from -40°C to 85°C.

Inverter Gates Procurement Notes

Verify the specific manufacturer source, as National Semiconductor is now part of Texas Instruments. Confirm RoHS compliance status, as documentation indicates non-compliance for some variants. Check part status carefully, as listings may indicate discontinued or obsolete stock. Ensure the package type matches the required 14-pin DIP form factor for your PCB layout.

Inverter Gates Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for CMOS logic families. Consider the 4.5V to 5.5V supply constraint against your system voltage. Evaluate the 4mA output drive capability against load requirements. Compare against standard push-pull NAND gates if open-drain characteristics are not specifically needed for bus sharing.

Inverter Gates Part Context

This component belongs to the HC/UH series of high-speed CMOS logic devices. It is functionally related to other NAND gates in the family but distinguished by its open-drain output stage. The MM prefix typically denotes commercial temperature range variants compared to military grade parts.

Inverter Gates Replacement Considerations

Substitutes must be quad 2-input open-drain NAND gates in 14-pin packages. Verify pinout compatibility and electrical specifications such as supply voltage and drive current. Common alternatives include other manufacturers' HC-series equivalents with identical logical functions.
