Substitute Part Grouping Explanation

Substitution for the 74ALVC373D,112 is determined by strict alignment of the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8 channel
• Output Type: Tri-State
• Supply Voltage Range: 1.65V ~ 3.6V
• Package Type: 20-SOIC form factor
• Output Current: 24mA (both high and low)
• Operating Temperature Range: -40°C ~ 85°C
• Compliance: ROHS3, MSL Level 1

The substitute parts identified below meet these core electrical and mechanical requirements. Propagation delay variations within the specified operating parameters do not preclude functional equivalence in most applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the 74ALVC373D,112. The SN74ALVCH373DW and SN74ALVCH373DWR (Texas Instruments 74ALVCH series) offer improved propagation delay performance at 1ns compared to the original 2.2ns specification, while the SN74LVC573ADW (Texas Instruments 74LVC series) provides a propagation delay of 2ns, closely matching the original part.

All substitute parts carry Active product status, ensuring long-term availability and manufacturing support. All parts maintain ROHS3 compliance and MSL Level 1 rating, meeting current regulatory and environmental requirements. Packaging format options include Tube and Tape & Reel configurations to accommodate different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH373DW replace the 74ALVC373D,112 in existing designs?

A: Yes. The SN74ALVCH373DW meets all critical electrical parameters: identical supply voltage range (1.65V ~ 3.6V), output current (24mA), operating temperature range (-40°C ~ 85°C), and package form factor (20-SOIC). The faster propagation delay (1ns vs. 2.2ns) is a performance enhancement and does not create compatibility issues.

Q: What is the difference between SN74ALVCH373DW and SN74ALVCH373DWR?

A: Both parts are electrically identical. The primary difference is packaging format: SN74ALVCH373DW is supplied in Tube format, while SN74ALVCH373DWR is supplied in Tape & Reel (TR) format. Selection depends on procurement volume and assembly line requirements.

Q: Is the SN74LVC573ADW a suitable alternative?

A: Yes. The SN74LVC573ADW maintains all required electrical specifications and package compatibility. The propagation delay of 2ns is marginally faster than the original 2.2ns, representing a minor performance improvement. This part belongs to the 74LVC series rather than 74ALVCH, but meets all substitution criteria.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All substitute parts carry identical ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications as the original 74ALVC373D,112.

Q: Which substitute part should be selected for new production?

A: Selection should be based on packaging requirements and supply chain availability. The SN74ALVCH373DW and SN74ALVCH373DWR offer superior propagation delay performance. The SN74LVC573ADW provides a closer match to original timing specifications. All three parts are Active status components with established long-term availability.
