SNJ54LS28W

Inverter Gates Overview

The SNJ54LS28W is a quadruple 2-input positive-NOR buffer manufactured by Texas Instruments. It belongs to the LS (Low-power Schottky) logic family and utilizes a ceramic flatpack (CDFP14) package with glass-sealed construction. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. It supports an extended industrial temperature range from -55 °C to 125 °C. Key electrical characteristics include a maximum propagation delay of 15 ns and a maximum power supply current of 2.2 mA.

Inverter Gates Feature Summary

• Quadruple 2-input positive-NOR buffer configuration
• Low-power Schottky (LS) logic technology for high-speed performance
• Ceramic flatpack package with glass-sealed construction for durability

Inverter Gates Applications

• Military and aerospace electronic systems requiring extended temperature tolerance
• Industrial control logic circuits
• High-reliability digital buffering applications

Inverter Gates Procurement Notes

Verify the specific suffix 'W' confirms the ceramic flatpack package variant. Confirm the manufacturer is Texas Instruments or an authorized licensee. Ensure the component meets military-grade specifications if required for the application environment. Check for RoHS compliance status as legacy LS parts may have specific regulatory classifications.

Inverter Gates Selection Notes

Select this component when a quadruple NOR buffer is required in a ruggedized environment. The LS series offers a balance of speed and power consumption suitable for general-purpose logic. The ceramic package provides superior thermal and mechanical stability compared to plastic alternatives. Ensure the design accommodates the 5 V nominal supply voltage constraints.

Inverter Gates Part Context

This part is part of the SN54/74LS series, a widely used standard logic family known for its robustness. The SNJ prefix typically denotes a military or high-reliability grade version produced by Texas Instruments. It serves as a fundamental building block for complex digital logic designs requiring NOR functionality.

Inverter Gates Replacement Considerations

Compatible substitutes include other manufacturers' SN54LS28 variants in CDFP14 packages. Verify pinout compatibility and electrical parameters such as propagation delay and supply current before substitution.
