Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC163PW,112 is determined by the following critical parameters:

Functional Compatibility Requirements:

• Logic Type: Binary Counter
• Number of Bits per Element: 4
• Direction: Up
• Reset Type: Synchronous
• Timing: Synchronous
• Trigger Type: Positive Edge
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Electrical Operating Range Compatibility:

• Voltage - Supply range must overlap or encompass the original specification
• Count Rate must meet or exceed application requirements
• Operating Temperature range must support the intended thermal environment

The SN74LV163APW from Texas Instruments meets all functional compatibility requirements and shares the identical 16-TSSOP package footprint. Both parts operate as 4-bit synchronous binary counters with positive edge triggering and synchronous reset. The substitute part operates within a different voltage range (2 V ~ 5.5 V) and has a lower maximum count rate (90 MHz) compared to the original specification (150 MHz), requiring design verification for specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

The SN74LV163APW qualifies as a functional substitute based on matching logic architecture, pin configuration, and package footprint. Both parts are ROHS3 compliant and carry MSL Level 1 ratings, supporting equivalent environmental and regulatory requirements.

Design considerations for substitution:

The SN74LV163APW operates at a maximum count rate of 90 MHz, which is lower than the 74LVC163PW,112 specification of 150 MHz. Applications requiring count rates above 90 MHz must be evaluated against the substitute part's performance envelope.

The voltage supply range differs between parts. The 74LVC163PW,112 operates from 1.2 V to 3.6 V, while the SN74LV163APW operates from 2 V to 5.5 V. Circuit designs must confirm that the substitute part's voltage range aligns with the system power supply specifications.

The operating temperature range of the SN74LV163APW extends to 85°C maximum, compared to 125°C for the original part. Applications requiring operation above 85°C require alternative solutions.

Both parts share identical package geometry and mounting type, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV163APW directly replace the 74LVC163PW,112 in all applications?

A: Direct replacement requires confirmation that the application's count rate requirement does not exceed 90 MHz, the system voltage supply falls within 2 V to 5.5 V, and the maximum operating temperature does not exceed 85°C. The 16-TSSOP package footprint is identical, enabling PCB-level compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are maximum count rate (150 MHz vs. 90 MHz), supply voltage range (1.2 V ~ 3.6 V vs. 2 V ~ 5.5 V), and maximum operating temperature (125°C vs. 85°C). Functional logic architecture and pin configuration are identical.

Q: Are both parts RoHS compliant?

A: Both the 74LVC163PW,112 and SN74LV163APW are ROHS3 compliant and carry MSL Level 1 moisture sensitivity ratings.

Q: Does the package footprint differ between these parts?

A: No. Both parts use the 16-TSSOP package with 0.173" width and 4.40mm dimensions, enabling direct PCB footprint compatibility without layout changes.

Q: What is the product status of each part?

A: The 74LVC163PW,112 is classified as Obsolete. The SN74LV163APW is listed as Discontinued at DiGi Electronics. Both parts require substitution planning for long-term design support.
