Engineering Selection Recommendations

Primary Recommendation: 74LVC273PW,118

The 74LVC273PW,118 from Nexperia USA Inc. is the preferred substitute for the obsolete 74LVC273PW,112. Both parts share identical electrical specifications, including supply voltage range (1.65V ~ 3.6V), clock frequency (230 MHz), propagation delay (8.2ns @ 3.3V, 50pF), and output current ratings (24mA). The 74LVC273PW,118 maintains Active product status, ensuring long-term availability and supply chain continuity. Both parts comply with ROHS3 and REACH requirements. The primary difference is packaging format: the 74LVC273PW,118 is supplied in Tape & Reel configuration, which is standard for production environments.

Secondary Recommendation: 74LVC273AT20-13

The 74LVC273AT20-13 from Diodes Incorporated is an alternative substitute with Active product status. This part maintains identical core specifications including 8-bit D-Type configuration, 230 MHz clock frequency, and 1.65V ~ 3.6V supply voltage range. The propagation delay is marginally improved at 7.3ns @ 3.3V, 50pF. Input capacitance is reduced to 4 pF compared to 5 pF in the original part. The Moisture Sensitivity Level is rated at MSL 3 (168 Hours), which differs from the original part's MSL 1 (Unlimited). This part is supplied in Tape & Reel packaging and is suitable for applications where the improved propagation delay is beneficial.

Alternative Consideration: SN74LV273APW

The SN74LV273APW from Texas Instruments is not recommended as a direct substitute. Although it maintains the same 20-TSSOP package and 8-bit D-Type configuration, it operates under different electrical parameters. The supply voltage range extends to 5.5V (versus 3.6V maximum for the original), clock frequency is reduced to 160 MHz, propagation delay is increased to 11ns @ 5V, and output current is reduced to 12mA. Additionally, this part is Discontinued at DiGi Electronics, limiting availability. This part should only be considered if the application specifically requires the extended voltage range and can tolerate reduced performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC273PW,118 be used as a direct replacement for the 74LVC273PW,112?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, including supply voltage (1.65V ~ 3.6V), clock frequency (230 MHz), propagation delay (8.2ns @ 3.3V, 50pF), and output current ratings (24mA). The primary difference is packaging format: the 74LVC273PW,118 is supplied in Tape & Reel, while the original was supplied in a different packaging variant. Both are 20-TSSOP surface mount packages with identical pinouts and footprints.

Q: What are the key differences between the 74LVC273AT20-13 and the original 74LVC273PW,112?

A: The 74LVC273AT20-13 maintains functional equivalence with identical supply voltage, clock frequency, and output current specifications. The measurable differences are: propagation delay is improved (7.3ns versus 8.2ns @ 3.3V, 50pF), input capacitance is reduced (4 pF versus 5 pF), and Moisture Sensitivity Level is MSL 3 (168 Hours) versus MSL 1 (Unlimited). The manufacturer is Diodes Incorporated rather than Nexperia. All parts share the same 20-TSSOP package and pinout.

Q: Why is the SN74LV273APW not recommended as a substitute?

A: The SN74LV273APW operates under different electrical parameters that make it unsuitable as a direct replacement. The clock frequency is reduced to 160 MHz (versus 230 MHz), propagation delay is increased to 11ns @ 5V (versus 8.2ns @ 3.3V), and output current is reduced to 12mA (versus 24mA). Additionally, this part is Discontinued at DiGi Electronics, limiting future availability. It should only be considered if the application requires the extended voltage range (2V ~ 5.5V) and can tolerate reduced performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts—74LVC273PW,118, 74LVC273AT20-13, and SN74LV273APW—are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original 74LVC273PW,112.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The original 74LVC273PW,112 and the 74LVC273PW,118 are rated MSL 1 (Unlimited), meaning they have no time restrictions for storage in non-controlled environments. The 74LVC273AT20-13 is rated MSL 3 (168 Hours), which requires that the component be used within 168 hours of opening the moisture barrier bag if stored in uncontrolled humidity conditions. For most production environments with proper moisture control, this difference is not significant.

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

A: Yes, all substitute parts use the identical 20-TSSOP (0.173", 4.40mm Width) package with the same pinout and footprint. PCB designs do not require modification. The primary consideration is ensuring that the application's electrical requirements fall within the specified parameters of the chosen substitute part.
