SNJ54H22W

Inverter Gates Overview

The SNJ54H22W is a dual 4-input NAND gate from the TTL/H/L series manufactured by Texas Instruments. It features complementary outputs and is housed in a CDFP14 ceramic flatpack package with 14 pins. The device operates within a temperature range of -55°C to 125°C and supports a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a maximum propagation delay of 20 ns and a maximum supply current of 38 mA. It is classified as RoHS non-compliant and has a moisture sensitivity level of 3.

Inverter Gates Feature Summary

• Dual 4-input NAND logic functionality
• Complementary output configuration
• Hermetically sealed ceramic flatpack construction
• Extended industrial temperature range capability

Inverter Gates Applications

• Military aerospace digital systems
• Industrial control logic circuits
• High-reliability computing hardware

Inverter Gates Procurement Notes

Verify component authenticity due to potential availability of unsorted or refurbished units from third-party distributors. Confirm package integrity, as hermetic seals are critical for the specified environmental ratings. Check for RoHS compliance status if required by specific project regulations, noting this part is generally non-compliant. Ensure storage conditions respect the MSL 3 rating to prevent moisture-induced damage during soldering.

Inverter Gates Selection Notes

Select this component when dual 4-input NAND logic is required in harsh environments demanding hermetic sealing. It is suitable for applications where standard plastic packages cannot withstand extreme temperatures or radiation. Consider the larger footprint and higher cost compared to commercial equivalents. Verify that the TTL/H/L series speed and power characteristics meet the system timing requirements.

Inverter Gates Part Context

This part belongs to the Texas Instruments 54-series military-grade logic family. It is functionally similar to the commercial 74H22 but offers enhanced reliability and wider operating temperature ranges. The SNJ prefix typically denotes a specific packaging or qualification variant within the broader 54H22 product line.

Inverter Gates Replacement Considerations

Direct substitutes include other 54H22 variants with compatible pinouts and specifications. Commercial equivalents like the 74H22 may be used if environmental constraints allow. Verify pin compatibility and electrical parameters before substitution.
