SNJ54F32FK

Inverter Gates Overview

The SNJ54F32FK is a military-grade quadruple 2-input positive-OR gate from the F/FAST series, 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 of -55 °C to 125 °C. The device utilizes a 20-pin LCCC (FK) package with a ceramic construction. Electrical characteristics include a maximum propagation delay of 7.5 ns at 5 V, a low-level output current capability of 20 mA, and a high-level output current of -1 mA.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates performing Boolean functions in positive logic
• Designed for full military temperature range operation from -55 °C to 125 °C
• Features high-speed switching characteristics suitable for fast digital applications

Inverter Gates Applications

• Military and defense electronic systems requiring radiation-hardened or high-reliability logic
• Aerospace control units operating under extreme environmental conditions
• High-speed data processing circuits utilizing standard TTL-compatible logic levels

Inverter Gates Procurement Notes

Verify that the specific part number matches the required military qualification standards and package type. Confirm the lead finish and material compliance requirements against project specifications. Ensure the supplier provides traceability documentation consistent with MIL-PRF-38535 or equivalent military procurement protocols. Check for any specific handling instructions related to the ceramic LCCC package.

Inverter Gates Selection Notes

Select this component when a quadruple 2-input OR function is required in harsh environments. The F-series offers faster switching speeds compared to LS or HC families. The FK package provides a hermetic seal suitable for long-term reliability in aerospace or defense sectors. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage constraints and thermal management needs.

Inverter Gates Part Context

This device belongs to the SN54F32 family of quadruple 2-input positive-OR gates. The 'SNJ' prefix indicates a military-grade ceramic dual in-line or leadless carrier package variant. The 'F' suffix denotes the FAST logic family, characterized by higher speed performance. The 'FK' specifically identifies the 20-pin Leadless Ceramic Chip Carrier package configuration.

Inverter Gates Replacement Considerations

Direct replacements include other SNJ54F32 variants with different packages such as SNJ54F32J (CDIP) or SNJ54F32W (CFP). Cross-family alternatives like SN54HC32 offer similar functionality but with different speed and power characteristics. Verify pinout compatibility and electrical parameters before substituting.
