Parameter Comparison

Engineering Selection Recommendations

74HC393D,653 (Nexperia USA Inc.): This part is a parametric equivalent manufactured by the same supplier as the main part. It maintains identical electrical specifications, including the 107 MHz count rate and -40°C ~ 125°C operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating. Selection of this substitute is appropriate when supply of the 74HC393D-Q100J is constrained, as it provides direct functional equivalence with no performance trade-offs.

MC74HC393ADR2G (onsemi): This part is manufactured by onsemi and meets all core compatibility criteria: 2-element, 4-bit binary counter with negative edge triggering, asynchronous reset, 14-SOIC package, 2 V ~ 6 V supply voltage, and ROHS3 compliance. The operating temperature range extends to -55°C (lower limit), providing enhanced cold-temperature performance. The count rate specification is 50 MHz, which is lower than the main part's 107 MHz. This substitute is suitable for applications where the lower count rate does not constrain system performance and extended low-temperature operation is beneficial. Both parts maintain identical MSL 1 rating and active product status.

Frequently Asked Questions (FAQ)

Q: Can 74HC393D,653 be used as a direct replacement for 74HC393D-Q100J? A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical and mechanical specifications, including count rate (107 MHz), operating temperature range (-40°C ~ 125°C), supply voltage (2 V ~ 6 V), and 14-SOIC package. No design modifications are required.

Q: What is the key difference between MC74HC393ADR2G and the main part? A: MC74HC393ADR2G is manufactured by onsemi and has a specified count rate of 50 MHz compared to 107 MHz for the main part. The operating temperature range extends to -55°C. All other electrical and mechanical parameters, including package type, supply voltage, and logic function, are identical.

Q: Is MC74HC393ADR2G suitable for automotive applications? A: MC74HC393ADR2G is ROHS3 compliant and meets the same supply voltage and operating temperature requirements as automotive-grade logic ICs. However, the main part carries AEC-Q100 qualification, which is a specific automotive industry standard. Verify AEC-Q100 requirement with your design specifications before selecting MC74HC393ADR2G.

Q: Are all substitute parts available in the same package? A: Yes. All three parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints and assembly processes are identical across all substitutes.

Q: What does MSL 1 (Unlimited) mean for these parts? A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life under standard storage conditions and do not require special moisture-control handling during storage or assembly.

Q: Can I use MC74HC393ADR2G in a high-frequency application requiring 107 MHz operation? A: MC74HC393ADR2G is specified for 50 MHz maximum count rate. Applications requiring 107 MHz operation should use 74HC393D-Q100J or 74HC393D,653 to ensure specified performance.
