Parameter Comparison

Engineering Selection Recommendations

SN74HC368PWR (Texas Instruments) is the primary substitute for the discontinued SN74HC368PW. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are packaged in 16-TSSOP surface mount configuration. The SN74HC368PWR maintains Active product status with higher inventory availability (4020 Pcs), making it the preferred selection for new designs and production continuity. Both parts are ROHS3 compliant with MSL 1 rating.

MC74HC368ADTR2G (onsemi) provides an alternative substitute manufactured by onsemi. This part maintains functional and electrical equivalence with identical logic type, element configuration, output type, and current specifications. The MC74HC368ADTR2G features an extended operating temperature range (-55°C ~ 125°C) compared to the original specification (-40°C ~ 85°C), providing broader thermal performance capability. However, the part is classified as Obsolete. This substitute is suitable for applications requiring extended temperature operation within the specified voltage range.

Frequently Asked Questions (FAQ)

Q: Can SN74HC368PWR be used as a direct replacement for SN74HC368PW?

A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, pin configuration, and 16-TSSOP package. The SN74HC368PWR is functionally equivalent and pin-compatible for direct substitution.

Q: What is the difference between the packaging designations "Tube" and "Cut Tape (CT) & Digi-Reel®"?

A: Packaging designation refers to the supply format. Tube packaging contains parts in a plastic tube, while Cut Tape and Digi-Reel® are continuous tape formats. Both formats contain identical components; the difference is in quantity and handling method for automated assembly processes.

Q: Is MC74HC368ADTR2G suitable for applications with the original -40°C ~ 85°C temperature specification?

A: Yes. The MC74HC368ADTR2G operates across -55°C ~ 125°C, which encompasses the original -40°C ~ 85°C range. The extended temperature capability does not affect compatibility within the original specification range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SN74HC368PWR and MC74HC368ADTR2G are both ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's environmental compliance status.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts maintain identical 16-TSSOP package dimensions (0.173", 4.40mm Width) and surface mount configuration, enabling direct PCB layout compatibility without design modification.
