Engineering Selection Recommendations

74LCX38MTCX is the primary recommended substitute for the 74LVC38APW,118. This part maintains active product status with Fairchild Semiconductor, ensuring long-term availability and supply chain stability. The 74LCX38MTCX provides identical logic configuration, open drain output, and 14-TSSOP packaging. While the supply voltage range is narrower (2V ~ 3.6V versus 1.2V ~ 5.5V) and the maximum operating temperature is reduced to 85°C, these parameters remain suitable for standard industrial and commercial applications operating within typical voltage and temperature ranges.

74LCX38MTC serves as an alternative substitute where specific package or inventory requirements differ. However, limited parameter documentation for this variant necessitates verification against application-specific requirements prior to implementation.

Both substitutes share identical export compliance classifications (ECCN: EAR99; HTSUS: 8542.39.0001) with the original part, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the 74LCX38MTCX directly replace the 74LVC38APW,118 on existing PCBs?

A: Yes. Both parts use the 14-TSSOP package with identical physical dimensions and pin configuration, enabling direct board-level substitution without layout modifications.

Q: What are the key electrical differences between the main part and 74LCX38MTCX?

A: The 74LCX38MTCX operates at a narrower supply voltage range (2V ~ 3.6V versus 1.2V ~ 5.5V), exhibits lower quiescent current (10 µA versus 40 µA), and has a reduced maximum operating temperature (85°C versus 125°C). Input and output logic levels remain compatible.

Q: Is the 74LCX38MTCX suitable for applications requiring the full 1.2V to 5.5V supply range of the original part?

A: No. Applications requiring operation below 2V or above 3.6V supply voltage must retain the original 74LVC38APW,118 or identify alternative solutions outside the 74LCX series.

Q: What is the significance of the open drain output configuration?

A: Open drain outputs require external pull-up resistors to establish high logic levels. This configuration is maintained across all substitute parts, ensuring functional compatibility with existing circuit designs.

Q: Are there packaging or compliance differences between substitutes?

A: Both 74LCX38MTC and 74LCX38MTCX maintain identical ECCN and HTSUS classifications. The 74LCX38MTCX is specified in bulk packaging, while the 74LCX38MTC packaging format is not detailed in available documentation.
