SNJ54ALS08J

Inverter Gates Overview

The SNJ54ALS08J is a military-grade quadruple 2-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from -55 °C to 125 °C. The device utilizes a 14-pin Ceramic Dual In Line (CDIP) package. Electrical characteristics include a maximum propagation delay of 14 ns at 4.5 V to 5.5 V with a 50 pF load, a low-level output current capability of up to 8 mA, and a high-level output current of -0.4 mA.

Inverter Gates Feature Summary

• Contains four independent 2-input positive-AND gates performing Boolean functions Y = A • B or Y = A + B in positive logic
• Characterized for full military temperature operation ranging from -55 °C to 125 °C
• Hermetically sealed ceramic dual in line packaging suitable for harsh environments

Inverter Gates Applications

• Military and defense electronic systems requiring radiation-hardened or high-reliability logic components
• Avionics control circuits operating under extreme thermal conditions
• Spacecraft instrumentation and communication subsystems

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum to confirm the exact package type and material specifications. Ensure that the procurement source provides documentation confirming QML certification status if required for military applications. Cross-reference the part marking with the official datasheet to validate authenticity and traceability before integration into production designs.

Inverter Gates Selection Notes

Select this component when designing systems that require hermetic sealing and extended temperature tolerance beyond standard commercial limits. Compare propagation delays and output drive currents against system timing requirements to ensure compatibility with existing logic families. Consider the physical dimensions of the CDIP package during PCB layout to accommodate through-hole mounting constraints.

Inverter Gates Part Context

This device belongs to the SN54ALS08 family, which includes variants such as SN54AS08 and commercial equivalents like SN74ALS08. The SNJ54ALS08J specifically denotes the military-grade version housed in a ceramic DIP package. It shares functional similarities with other AND gate series but offers distinct environmental robustness and reliability standards defined by Texas Instruments for aerospace and defense sectors.

Inverter Gates Replacement Considerations

Direct substitutes include SNJ54AS08J for faster switching speeds and SNJ54LS08J for lower power consumption, provided pinout and voltage levels remain compatible. Verify that alternative packages maintain the same footprint and thermal characteristics for direct board replacement.
