SNJ54H55W

Inverter Gates Overview

The SNJ54H55W is a high-speed logic component from Texas Instruments, classified as an AND-OR-INVERT gate within the H series. It features complementary outputs and is housed in a ceramic flatpack (CDFP16) package with 16 terminals. The device operates over an extended temperature range of -55 °C to 125 °C. Key electrical specifications include a maximum propagation delay of 20 ns and a maximum supply current of 38 mA at a nominal 5 V supply voltage.

Inverter Gates Feature Summary

• Provides AND-OR-INVERT logic functionality with complementary output signals
• Constructed using ceramic flatpack packaging for durability
• Engineered for operation across extreme military-grade temperature ranges

Inverter Gates Applications

• Military aerospace digital systems
• High-reliability industrial control logic
• Harsh environment data processing circuits

Inverter Gates Procurement Notes

Verify the specific suffix 'W' indicates the ceramic flatpack variant when sourcing. Confirm the manufacturer source is authorized to ensure authenticity of the Texas Instruments part. Check for RoHS compliance status if required by your assembly process, noting that legacy military parts may have different regulatory profiles than standard commercial equivalents.

Inverter Gates Selection Notes

Select this component when a robust AND-OR-INVERT function is required in environments exceeding standard commercial temperature limits. The ceramic package offers superior thermal and mechanical stability compared to plastic alternatives. Ensure the design accommodates the 5 V supply requirement and the specific pinout of the CDFP16 footprint during PCB layout.

Inverter Gates Part Context

This part belongs to the Texas Instruments H series of TTL logic devices, designed for high-speed applications. The SNJ prefix typically denotes a military-grade qualification level, ensuring performance consistency under rigorous conditions. It serves as a fundamental building block for complex combinational logic in critical systems where reliability is paramount.

Inverter Gates Replacement Considerations

Direct substitutes must match the H series logic family and CDFP16 ceramic package. Verify pin compatibility and electrical characteristics such as propagation delay and supply current. Generic plastic packages are not suitable replacements due to the environmental rating differences.
