- Number of circuits: 4
- Multiplexer/Demultiplexer configuration: 1:1
- Package type: 16-SOIC surface mount
- Supply voltage compatibility: 4.5V ~ 5.5V (single) or ±1V ~ 5V (dual)
- Operating temperature range: -55°C ~ 125°C minimum
- RoHS3 compliance and MSL 1 rating
Secondary Compatibility Parameters:

Engineering Selection Recommendations
CD74HCT4316M96 (MFR Recommended) This Texas Instruments part is the direct equivalent with identical electrical specifications to the main part. It maintains 170Ohm on-state resistance, 5Ohm channel matching, and 200MHz bandwidth. Current product status is Last Time Buy, indicating limited availability. This part is suitable for direct replacement in existing designs.
CD74HCT4316MT (Parametric Equivalent) This Texas Instruments variant provides identical electrical performance to the main part across all critical parameters. Product status is Discontinued at DiGi Electronics. Inventory availability is 1013 units. This part is electrically interchangeable but may have limited long-term supply.
74HCT4316D,118 (Nexperia USA Inc.) This part maintains the same 4-circuit SPST-NO configuration and 1:1 multiplexer architecture in 16-SOIC packaging. On-state resistance is 135Ohm (lower than the main part), with 6Ohm channel matching. Bandwidth is reduced to 160MHz. Operating temperature minimum is -40°C (versus -55°C for the main part). Product status is Active with 3313 units in stock. This part is suitable for applications where lower on-state resistance is beneficial and the narrower temperature range is acceptable.
NLV74HC4316ADR2G (onsemi) This part provides a 4-circuit 1:1 multiplexer in 16-SOIC packaging with significantly lower on-state resistance of 90Ohm. Supply voltage range is broader (2V ~ 6V single, ±2V ~ 6V dual). The part carries AEC-Q100 automotive qualification. Product status is Obsolete. This part is suitable only for applications where the lower on-state resistance is required and long-term supply is not critical.
Frequently Asked Questions (FAQ)
Q: Can CD74HCT4316M96 be used as a direct replacement for CD74HCT4316M96G4? A: Yes. CD74HCT4316M96 is the direct equivalent with identical electrical specifications, package type, and supply voltage requirements. The primary difference is packaging format (Tape & Reel versus individual unit) and product status (Last Time Buy versus Discontinued).
Q: What is the difference between CD74HCT4316M96 and 74HCT4316D,118? A: Both are 4-circuit SPST-NO switches in 16-SOIC packages. The Nexperia part (74HCT4316D,118) has lower on-state resistance (135Ohm versus 170Ohm), reduced bandwidth (160MHz versus 200MHz), and a narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). The Nexperia part is currently Active in production.
Q: Is NLV74HC4316ADR2G compatible with the original CD74HCT4316M96G4? A: NLV74HC4316ADR2G provides the same 4-circuit 1:1 multiplexer configuration and 16-SOIC package. However, it has significantly different electrical characteristics: 90Ohm on-state resistance (versus 170Ohm), broader supply voltage range, and automotive qualification. The part is obsolete. Compatibility depends on application-specific requirements for on-state resistance and supply voltage.
Q: What packaging options are available for these substitutes? A: All substitute parts are available in 16-SOIC surface mount packages with 0.154" (3.90mm) width. CD74HCT4316M96 is supplied in Tape & Reel format. Packaging format does not affect electrical compatibility.
Q: Which substitute part has the best current availability? A: 74HCT4316D,118 (Nexperia) has the highest inventory with 3313 units in stock and Active product status. CD74HCT4316M96 has 4194 units available but is in Last Time Buy status. NLV74HC4316ADR2G has 3469 units but is Obsolete.
Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original CD74HCT4316M96G4.
