74LVC823APW,118 Equivalent & Substitute Parts

Part Overview

The 74LVC823APW,118 is a single-element D-type flip-flop with 9-bit configuration and tri-state, non-inverted output, manufactured by Nexperia USA Inc. in 24-TSSOP surface mount packaging. This logic component operates across a 1.65V to 3.6V supply voltage range with a maximum propagation delay of 10ns at 3.3V with 50pF load. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC823APW,118 is determined by the following critical parameters:

Primary Substitution Criteria:

• D-Type flip-flop architecture with tri-state, non-inverted output
• 9-bit configuration (or compatible bit width)
• 24-TSSOP or equivalent surface mount package
• Voltage supply range: 1.65V ~ 3.6V
• Output current capability: 24mA minimum (both high and low)
• Quiescent current: 10 µA maximum
• Operating temperature range: minimum -40°C to +85°C or better

Secondary Compatibility Factors:

• Propagation delay performance at 3.3V with 50pF load
• Clock frequency rating
• Trigger type: Positive Edge
• Function: Master Reset capability

Substitute parts must maintain compatibility across all primary criteria. Variations in clock frequency or propagation delay are acceptable provided the part meets or exceeds the minimum performance threshold for the application.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement):

The SN74LVC823APW, SN74LVC823APWR, and SN74LVC823APWT from Texas Instruments are functionally equivalent to the 74LVC823APW,118. All three maintain identical electrical specifications, package footprint (24-TSSOP), and 9-bit configuration. These parts are currently in active production status and ROHS3 compliant. Selection among these three should be based on packaging requirements: SN74LVC823APW is supplied in Tube packaging, while SN74LVC823APWR and SN74LVC823APWT are supplied in Tape & Reel format. The Tape & Reel variants are preferred for high-volume manufacturing applications.

Secondary Substitute (Conditional):

The SN74LVC821ADGVR from Texas Instruments is a 10-bit variant with improved propagation delay (7.3ns versus 10ns). This part is suitable only when the application can accommodate the additional bit width and does not require the extended operating temperature range (-40°C to +125°C). The 24-TFSOP package is mechanically compatible with 24-TSSOP footprints. This substitute is appropriate for applications where the extra bit capacity provides functional benefit.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements. Moisture sensitivity level remains at MSL 1 (Unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC823APWR directly replace the 74LVC823APW,118 in existing designs?

A: Yes. The SN74LVC823APWR is a direct functional equivalent with identical electrical specifications, package footprint, and pin configuration. The primary difference is the packaging format (Tape & Reel versus the original Tube format), which does not affect circuit performance.

Q: What is the difference between the 9-bit 74LVC823 and the 10-bit SN74LVC821ADGVR?

A: The SN74LVC821ADGVR provides one additional bit of storage capacity and faster propagation delay (7.3ns versus 10ns). It is suitable for replacement only if the application design can utilize the extra bit or if improved timing performance is beneficial. The package footprint is mechanically compatible.

Q: Are all substitute parts available in the same package?

A: The SN74LVC823 variants (APW, APWR, APWT) use 24-TSSOP packaging identical to the original. The SN74LVC821ADGVR uses 24-TFSOP packaging, which is mechanically compatible but has different pin assignments. Verify pinout compatibility before substitution.

Q: Does the reduced operating temperature range of the Texas Instruments substitutes affect compatibility?

A: The Texas Instruments substitutes operate from -40°C to +85°C, compared to the original -40°C to +125°C range. Substitution is appropriate only if the application does not require operation above +85°C. For high-temperature applications, the original Nexperia part or alternative high-temperature logic families must be used.

Q: What packaging format should be selected for production applications?

A: For automated assembly and high-volume production, Tape & Reel format (SN74LVC823APWR or SN74LVC823APWT) is standard. Tube packaging (SN74LVC823APW) is suitable for lower-volume or manual assembly scenarios.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original 74LVC823APW,118.
