Engineering Selection Recommendations
CD4067BM96 (Texas Instruments) - Recommended Primary Substitute
CD4067BM96 is the preferred substitute for new designs and production continuity. It maintains CMOS technology compatibility with the original HEF4067BT,652, offers active product status with established supply chains, and supports the full 3V ~ 18V supply range. The 240Ohm on-state resistance and 14MHz bandwidth are suitable for standard multiplexing applications. ROHS3 compliance and MSL 1 rating ensure compatibility with modern manufacturing processes.
CD74HC4067M96 (Texas Instruments) - High-Performance Alternative
CD74HC4067M96 provides superior performance characteristics with 89MHz bandwidth and 160Ohm on-state resistance, making it suitable for higher-frequency signal routing applications. Active product status and broad supply availability support long-term production requirements. The narrower supply voltage range (2V ~ 6V) requires verification against system power specifications. ROHS3 compliance and MSL 1 rating are maintained.
CD74HCT4067M (Texas Instruments) - TTL-Compatible Option
CD74HCT4067M is specified for 5V-centric systems with TTL-level input compatibility. The 4.5V ~ 5.5V supply range is restrictive but appropriate for legacy 5V logic environments. Active product status and 89MHz bandwidth support both standard and higher-frequency applications. ROHS3 compliance and MSL 1 rating apply.
MC14067BDWR2G (onsemi) - Extended Supply Range Alternative
MC14067BDWR2G supports the widest supply voltage range (3V ~ 18V) and is available in Cut Tape & Digi-Reel packaging for high-volume production. Active product status ensures supply continuity. The 280Ohm on-state resistance and 15MHz bandwidth are acceptable for standard multiplexing. MSL 3 rating requires controlled storage conditions (168 hours at 60% RH, 30°C maximum).
MC14067BDWG (onsemi) - Tube Packaging Option
MC14067BDWG provides identical electrical specifications to MC14067BDWR2G with Tube packaging. Active product status and 3V ~ 18V supply range support flexible system designs. MSL 3 rating applies.
CD4067BM (Texas Instruments) - Last Time Buy Status
CD4067BM is classified as Last Time Buy and should be avoided for new production commitments. While electrically equivalent to CD4067BM96, declining availability and end-of-life status make it unsuitable for long-term supply assurance.
Frequently Asked Questions (FAQ)
Q: Can I directly replace HEF4067BT,652 with any of these substitutes?
A: All listed substitutes maintain the 16:1 multiplexer architecture, single-circuit configuration, and 24-SOIC package format. Direct pin-compatible replacement is possible. However, verify that your application's supply voltage, bandwidth, and on-state resistance requirements fall within the substitute's specifications.
Q: What is the primary difference between the substitute options?
A: The main differences are on-state resistance (155Ohm to 280Ohm), bandwidth (14MHz to 89MHz), supply voltage ranges (2V ~ 18V), and semiconductor process technology (CMOS vs. HC/HCT logic families). These variations reflect different design optimizations for power consumption, speed, and voltage flexibility.
Q: Which substitute offers the closest electrical match to HEF4067BT,652?
A: CD74HC4067M96 provides the closest performance match with 160Ohm on-state resistance and 89MHz bandwidth, closely approximating the original 155Ohm and 70MHz specifications. CD4067BM96 offers a practical balance of performance and supply availability.
Q: Are there supply voltage compatibility concerns?
A: The original HEF4067BT,652 operates at 3V ~ 15V. CD74HC4067M96 is limited to 2V ~ 6V, making it unsuitable for 15V applications. CD4067BM96, MC14067BDWR2G, and MC14067BDWG all support 3V ~ 18V ranges and are fully compatible with the original voltage specification.
Q: What does MSL 3 rating mean for MC14067 variants?
A: MSL 3 requires storage at ≤60% relative humidity and ≤30°C for a maximum of 168 hours before soldering. Exceeding these conditions requires baking at 125°C for 24 hours. MSL 1 parts (all Texas Instruments options) have unlimited shelf life and are preferred for inventory management.
Q: Can I use CD74HCT4067M in a 3V system?
A: No. CD74HCT4067M is specified for 4.5V ~ 5.5V operation and is not suitable for 3V systems. Use CD4067BM96, CD74HC4067M96, MC14067BDWR2G, or MC14067BDWG for 3V compatibility.
Q: What packaging options are available?
A: CD4067BM is supplied in Tube packaging. CD4067BM96, CD74HC4067M96, and MC14067BDWR2G are available in Cut Tape & Digi-Reel format for automated assembly. CD74HCT4067M and MC14067BDWG are supplied in Tube packaging. Select based on your production volume and assembly equipment requirements.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements.
