Engineering Selection Recommendations
Tier 1 - Direct Equivalents (Recommended Primary Substitutes):
CD74HCT4052M96 and CD74HCT4052MT are functionally identical Texas Instruments parts differing only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel). CD74HCT4052M96 is in Active product status with significantly higher inventory availability (28,367 units), making it the preferred substitute for new designs and procurement. Both maintain identical electrical specifications including 130Ohm on-state resistance, 185MHz bandwidth, and -55°C to 125°C operating temperature range.
Tier 2 - Compatible Substitutes (Nexperia Parts):
74HCT4052D,118 and 74HCT4052D-Q100,11 are Nexperia USA Inc. manufactured parts with identical switch configuration and circuit topology. These parts feature slightly higher on-state resistance (150Ohm maximum versus 130Ohm) and marginally reduced bandwidth (180MHz versus 185MHz). Operating temperature range is narrower (-40°C to 125°C versus -55°C to 125°C). The 74HCT4052D-Q100,11 variant includes AEC-Q100 automotive qualification. Both parts are in Active status with adequate inventory.
Tier 3 - Alternative Substitutes (Performance Trade-offs):
MC74HCT4052ADR2G (onsemi) offers superior on-state resistance performance (100Ohm maximum) but exhibits significantly higher channel capacitance (130pF versus 5pF/12pF) and reduced bandwidth (80MHz versus 185MHz). This part is suitable for applications where lower on-state resistance is critical and bandwidth requirements are less stringent. Operating temperature range matches the original part (-55°C to 125°C).
BU4052BCF-E2 (Rohm Semiconductor) features the widest supply voltage range (3V to 18V single supply) but has higher on-state resistance (160Ohm), narrower operating temperature range (-40°C to 85°C), and unspecified bandwidth. Package width differs (4.40mm versus 3.90mm), requiring PCB layout verification. This part is suitable only for applications with relaxed temperature and bandwidth requirements.
Product Status Consideration:
The CD74HCT4052MT is designated Last Time Buy, indicating end-of-life status. Immediate transition to CD74HCT4052M96 (Active status, same manufacturer) is recommended for design continuity and long-term supply assurance.
Frequently Asked Questions (FAQ)
Q: Can I use 74HCT4052D,118 as a direct replacement for CD74HCT4052MT?
A: 74HCT4052D,118 is functionally compatible with identical switch configuration and circuit topology. However, it exhibits 150Ohm on-state resistance versus 130Ohm, 180MHz bandwidth versus 185MHz, and a narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). Substitution is acceptable if your application does not require the lower resistance or extended low-temperature operation of the original part.
Q: What is the difference between CD74HCT4052MT and CD74HCT4052M96?
A: These are electrically identical Texas Instruments parts with identical specifications. The difference is packaging format: CD74HCT4052MT is supplied in Tape & Reel format, while CD74HCT4052M96 is supplied in Cut Tape & Digi-Reel format. CD74HCT4052M96 is in Active product status with higher inventory availability.
Q: Why does MC74HCT4052ADR2G have such high channel capacitance?
A: MC74HCT4052ADR2G is an onsemi variant with different internal design characteristics. The 130pF channel capacitance (versus 5pF/12pF in the original part) results in reduced bandwidth performance (80MHz versus 185MHz). This part is suitable only for lower-frequency applications where capacitance is not a limiting factor.
Q: Can BU4052BCF-E2 be used in applications requiring -55°C operation?
A: No. BU4052BCF-E2 has a minimum operating temperature of -40°C, making it unsuitable for applications requiring -55°C operation. The original CD74HCT4052MT and recommended substitute CD74HCT4052M96 both support -55°C to 125°C operation.
Q: Does package width difference between BU4052BCF-E2 (4.40mm) and CD74HCT4052MT (3.90mm) affect compatibility?
A: Yes. The 0.50mm width difference requires PCB layout verification. Pin spacing and footprint dimensions must be confirmed before substitution. Existing PCB designs may require modification to accommodate the wider package.
Q: What supply voltage range should I verify before substituting parts?
A: Verify that your application's supply voltage falls within the substitute part's specified range. CD74HCT4052MT, CD74HCT4052M96, and Nexperia parts support 4.5V to 5.5V single supply. MC74HCT4052ADR2G supports 2V to 6V. BU4052BCF-E2 supports 3V to 18V. Dual supply operation requires verification of ±1V to 5V (or ±2V to 6V for onsemi part) compatibility.
Q: Is the 74HCT4052D-Q100,11 suitable for automotive applications?
A: Yes. 74HCT4052D-Q100,11 includes AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. The original CD74HCT4052MT does not carry automotive qualification.
