SNJ54H30J

Inverter Gates Overview

The SNJ54H30J is a high-speed TTL logic gate manufactured by Texas Instruments, housed in a 14-lead ceramic dual-in-line package (CDIP). It contains one eight-input NAND function. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. Key electrical specifications include a maximum propagation delay of 12 ns and a maximum power supply current of 10 mA. It supports a load capacitance of 25 pF and functions reliably across an extended temperature range from -55 °C to +125 °C.

Inverter Gates Feature Summary

• Provides a single eight-input NAND logic function for complex boolean operations.
• Features high-speed performance with a 12 ns propagation delay characteristic.
• Constructed with a hermetically sealed ceramic package for environmental durability.

Inverter Gates Applications

• Military and aerospace digital systems requiring radiation-hardened or high-reliability components
• Industrial control logic circuits operating in extreme temperature environments
• High-speed data processing gates within TTL-based computing architectures

Inverter Gates Procurement Notes

Verify the specific ordering suffix and manufacturer documentation to confirm the exact variant matches the SNJ54H30J specifications. Ensure that the ceramic package integrity and lead configuration align with the required PCB footprint. Cross-reference the datasheet parameters against system requirements to validate compatibility with existing TTL logic families and power supply constraints.

Inverter Gates Selection Notes

Select this component when an eight-input NAND gate is required for high-speed applications within the military temperature range. The choice depends on the necessity for a single-function gate with significant input capacity compared to lower-input alternatives. Consider the CDIP package form factor for through-hole mounting and the specific power consumption profile relative to other TTL series options.

Inverter Gates Part Context

This part belongs to the Texas Instruments SN54 series, designed for military-grade reliability and wide temperature operation. It is distinct from commercial SN74 variants due to its enhanced thermal and operational specifications. The H-series designation indicates high-speed performance, differentiating it from standard or low-power logic families within the broader TTL ecosystem.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN54H30J and SN54LS30J, provided the speed and power trade-offs are acceptable. Verify pinout compatibility and logical equivalence before substitution to ensure circuit functionality remains intact without modification.
