SN74HC03NE4

Overview

The SN74HC03NE4 is a quadruple 2-input NAND gate with open-drain outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40 °C to +85 °C. The device features low power consumption with a maximum ICC of 20 µA, typical propagation delay of 8 ns at 5 V, and ±4-mA output drive capability. It utilizes standard CMOS inputs and is housed in a 14-pin PDIP package.

Feature Summary

• Contains four independent 2-input NAND gates performing the Boolean function Y = A · B
• Features open-drain outputs that sink current to ground but do not source current from VCC
• Supports wired-AND configurations due to non-sourcing output structure

Applications

• NAND OD logic circuits
• Direct LED control applications
• Voltage level translation (up-translation and down-translation)

Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance details. Ensure the procurement channel provides valid traceability for the active production status. Confirm the package type matches the required 14-pin DIP form factor for your assembly process.

Selection Notes

Select this component when open-drain logic functionality is required for bus systems or voltage translation. Verify that the external pull-up resistor limits the total sinking current to remain within the absolute maximum ratings. Ensure input signal edge rates are fast enough to prevent excessive shoot-through current associated with standard CMOS inputs.

Part Context

This part belongs to the SNx4HC03 family of quadruple 2-input NAND gates with open-drain outputs. It is designed for general-purpose digital logic applications requiring high noise immunity and low power consumption. The device is available in multiple packages including SOIC, SOP, TSSOP, and CDIP variants.

Replacement Considerations

SN74HC03N is a direct equivalent offering identical electrical characteristics and pinout configuration without the E4 suffix designation.
