Substitute Part Grouping Explanation

Substitution for the MM74HC4316MTC is determined by the following core parameters:

Functional Topology: SPST-NO switch circuit with 1:1 multiplexer/demultiplexer configuration and 4 circuits
Package Compatibility: 16-TSSOP surface mount package with identical 0.173" (4.40mm) width
Electrical Compatibility: Supply voltage ranges, on-state resistance, leakage current, and switching characteristics
Environmental Specifications: Operating temperature range and moisture sensitivity level

The three substitute parts listed below maintain the same functional topology and package form factor. Variations in on-state resistance, supply voltage ranges, switching times, and operating temperature ranges are documented to enable informed selection based on application requirements.

Engineering Selection Recommendations

CD74HC4316PWR (Texas Instruments) is the primary substitute for new designs. This part is actively manufactured, ROHS3 compliant, and available in Tape & Reel packaging with 6515 pieces in stock. It maintains identical functional topology and package form factor while offering extended operating temperature range (-55°C to 125°C) and higher -3dB bandwidth (200MHz). The increased on-state resistance (170Ohm versus 70Ohm) and longer switching times (37ns versus 14ns/20ns) must be evaluated against application requirements.

74HC4316PW,118 (Nexperia USA Inc.) is an active alternative with higher inventory availability (3513 pieces). This part provides intermediate on-state resistance (135Ohm) and faster switching times (16ns) compared to Texas Instruments variants, with extended operating temperature range (-40°C to 125°C) and ROHS3 compliance. Tape & Reel packaging is standard.

CD74HC4316PW (Texas Instruments) carries Last Time Buy status and is available in Tube packaging (1401 pieces in stock). This variant shares electrical specifications with CD74HC4316PWR but differs in packaging format. Selection of this part should account for its end-of-life status.

For applications requiring the lowest on-state resistance (70Ohm) and fastest switching times of the original MM74HC4316MTC, no direct equivalent exists among active products. Substitute selection must prioritize application-specific requirements for resistance, switching speed, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MM74HC4316MTC with CD74HC4316PWR in my design?

A: Direct replacement is possible from a package and functional topology perspective. Both are 4-circuit SPST-NO switches in 16-TSSOP packaging. However, the CD74HC4316PWR has higher on-state resistance (170Ohm versus 70Ohm) and longer switching times (37ns versus 14ns/20ns). Circuit performance must be evaluated to confirm these differences do not impact application requirements.

Q: What is the key difference between 74HC4316PW,118 and the Texas Instruments alternatives?

A: The 74HC4316PW,118 from Nexperia offers intermediate on-state resistance (135Ohm) and faster switching times (16ns) compared to Texas Instruments parts (170Ohm, 37ns). All three substitutes maintain identical package form factor and functional topology. Selection depends on whether the application can tolerate higher resistance and slower switching speeds.

Q: Are all substitute parts RoHS compliant?

A: The Texas Instruments variants (CD74HC4316PW and CD74HC4316PWR) are ROHS3 compliant. The Nexperia part (74HC4316PW,118) is also ROHS3 compliant. All parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity level.

Q: What packaging options are available for substitutes?

A: CD74HC4316PWR is supplied in Tape & Reel (TR) packaging. CD74HC4316PW is supplied in Tube packaging. 74HC4316PW,118 is supplied in Tape & Reel (TR) packaging. All maintain the same 16-TSSOP form factor.

Q: Which substitute has the best availability?

A: CD74HC4316PWR (Texas Instruments) has the highest inventory with 6515 pieces in stock and active product status, making it the most suitable choice for ongoing production requirements.
