SNJ54AS08J

Inverter Gates Overview

The SNJ54AS08J 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 high-level output current of -2 mA and a low-level output current of 20 mA at VCC = 4.5 V. Switching performance under a 50 pF load capacitance specifies propagation delay times with a maximum of 6.5 ns for both tPLH and tPHL transitions.

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
• Utilizes 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, such as CDIP (J), LCCC (FK), or CFP (W). Ensure the procurement specification explicitly requires the 'SNJ' prefix to guarantee the military-grade qualification and hermetic sealing associated with the 54-series designation rather than commercial variants.

Inverter Gates Selection Notes

Select this component when designing systems that require high-speed AND logic functionality within the AS series family. It is appropriate for applications demanding operation across the full military temperature spectrum where standard commercial logic devices would fail. Consider the higher drive current capabilities compared to LS series alternatives if driving heavier capacitive loads.

Inverter Gates Part Context

This part belongs to the Texas Instruments 54AS/74AS logic family, which offers faster switching speeds than the standard ALS series. The 'SNJ' designation indicates a military-qualified version housed in a ceramic DIP package. It serves as a high-performance logic solution for critical applications where speed and environmental robustness are primary design constraints.
