SNJ54 seems better

The difference between SN54 and SNJ54 series circuits:

Package form: The package form of SN54 series is DIP (dual in-line multi-pin chip), while the package form of SNJ54 series is SOP (single in-line multi-pin chip).

Reliability: The SNJ54 series has higher reliability than the SN54 series because it uses a more rigorous manufacturing process.

Applications: The SN54 series is more suitable for home appliances and industrial applications, while the SNJ54 series is more suitable for telecommunications and computer applications.

Explanation of the suffixes in SN54LSX XX /HC/HCT/ or SNJ54LS/HC/HCT: 1. SN or SNJ indicates TI brand 2. SN is a military standard. N indicates DIP package, J indicates DIP (dual in-line package), D indicates surface mount, and W indicates wide body 3. SNJ is a military grade. The suffix F or /883 at the end indicates an inspected military grade. CD54LSX XX /HC/HCT: 1. No suffix indicates general military grade 2. Suffix with J or 883 indicates military grade CD4000/CD45X X: 1. Suffix with BCP or BE is military grade 2. Suffix with BF is general military grade 3. Suffix with BF3A or 883 is military grade TLXX X: Suffix CP is general grade IP is industrial grade Suffix with D is surface mount Suffix with MJB, MJG or /883 is military grade TLC indicates general voltage TLV indicates low power voltage TMS320 series belongs to DSP devices, MSP43OF microprocessor

I don't agree with this. The 54 series is originally a military product, and the 74 series is used in household appliances.

Encapsulation is related to the suffix, not the prefix
