SNJ5403W

Inverter Gates Overview

The SNJ5403W is a quadruple 2-input positive-NAND gate featuring open-collector outputs, manufactured by Texas Instruments. It belongs to the SN54 series of logic gates designed for military-grade reliability and wide temperature operation ranging from -55°C to +125°C. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical characteristics include a maximum output current of 16mA, a typical low-level input current of 250uA, and a propagation delay of 45ns at 5V with a 15pF load. The package provides four independent NAND gates in a single unit.

Inverter Gates Feature Summary

• Quadruple 2-input configuration providing four independent NAND functions
• Open-collector output structure suitable for wired-logic applications
• Military-grade performance with extended temperature range capability

Inverter Gates Applications

• Military aerospace systems requiring high-reliability logic
• Industrial control systems operating in extreme temperatures
• Test and measurement equipment demanding precise timing

Inverter Gates Procurement Notes

Verify the specific suffix 'W' indicates the ceramic package variant when sourcing. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check datasheet revisions for any pinout or electrical specification updates. Ensure the supplier provides traceability documentation required for military or aerospace procurement standards.

Inverter Gates Selection Notes

Select this component when open-collector NAND functionality is required in harsh environments. Compare against standard commercial grades if temperature ranges are less critical. Consider power dissipation limits associated with the open-collector design. Verify compatibility with existing TTL/H/L series logic families in the system architecture.

Inverter Gates Part Context

This part is part of the SN54 series, which denotes military-grade specifications compared to the commercial SN74 series. It serves as a fundamental building block for digital logic circuits requiring robust performance under stress conditions. The open-collector output allows for flexible interfacing with different voltage levels through external pull-up resistors.

Inverter Gates Replacement Considerations

SN5403W is the commercial equivalent without the military suffix. SN54LS03 offers lower power consumption but different switching characteristics. Verify pin compatibility before substituting with other quad NAND gate variants.
