SNJ54ALS32FK

Inverter Gates Overview

The SNJ54ALS32FK is a military-grade quadruple 2-input positive-OR 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 20-pin Leadless Ceramic Chip Carrier (LCCC) package. Electrical characteristics include a maximum propagation delay of 18 ns at 4.5 V and 16 ns at 5.5 V, with low-level output current capabilities up to 8 mA.

Inverter Gates Feature Summary

• Contains four independent 2-input positive-OR gates performing Boolean functions in positive logic
• Characterized for full military temperature operation ranging from -55 °C to 125 °C
• Utilizes hermetically sealed ceramic construction suitable for harsh environments

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific ordering suffix FK to confirm the LCCC package configuration. Ensure procurement channels provide QML certified parts if military compliance is required. Confirm RoHS exemption status as indicated in the packaging data. Validate that the supplier can provide traceability documentation consistent with aerospace standards.

Inverter Gates Selection Notes

Select this component when designing systems requiring high-speed OR logic under severe environmental stress. The ALS series offers faster switching speeds compared to standard LS logic while maintaining lower power consumption than AS variants. Verify that the 20-pin LCCC footprint matches the PCB layout constraints and that the thermal management strategy accommodates the specified operating temperature range.

Inverter Gates Part Context

This part belongs to the SN54/74ALS32 family of quadruple 2-input positive-OR gates. The SNJ prefix indicates a military-grade ceramic package variant produced by Texas Instruments. It shares functional compatibility with other devices in the 54ALS logic family but is distinguished by its ruggedized construction and extended temperature specifications.

Inverter Gates Replacement Considerations

SNJ54AS32FK provides equivalent functionality with higher speed performance. SNJ54ALS32W serves as a pin-compatible alternative using a ceramic flatpack package. SNJ54ALS32J is available in a dual in-line package format.
