Engineering Selection Recommendations
Direct Replacement (Identical Electrical Performance):
CD4053BM96 is the primary direct replacement for CD4053BMT. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating temperature range (-55°C ~ 125°C), and supply voltage capabilities. CD4053BM96 is in Active product status, ensuring long-term availability. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect electrical performance.
Performance-Tier Substitutes (Lower On-State Resistance):
Parts with lower on-state resistance (74HC4053D,653 at 120Ohm, MC74HC4053ADG/ADR2G at 100Ohm, MC74LVX4053DR2G at 26Ohm) provide improved signal integrity and reduced power dissipation. These are suitable when the application can tolerate reduced supply voltage ranges or narrower operating temperature windows. MC74HC4053ADG and MC74HC4053ADR2G maintain the full -55°C ~ 125°C temperature range and are in Active status.
Compatibility-Constrained Substitutes:
MC14053BDR2G and MC14053BDG (280Ohm on-state resistance) are suitable only for applications operating within 3V ~ 18V single supply range without dual supply requirements. These parts exhibit reduced bandwidth (17MHz) and do not support dual supply operation.
HEF4053BT,653 (155Ohm on-state resistance) is suitable for applications within 3V ~ 15V single supply range. This part exhibits higher leakage current (200nA) and does not support dual supply operation.
74HCT4053D,118 is restricted to 4.5V ~ 5.5V single supply operation and is suitable only for TTL-compatible applications with this specific voltage requirement.
Compliance Verification:
All substitute parts listed maintain RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility with the original CD4053BMT.
Frequently Asked Questions (FAQ)
Q: Can CD4053BM96 be used as a direct replacement for CD4053BMT in all applications?
A: Yes. CD4053BM96 is electrically and functionally identical to CD4053BMT. Both parts share the same on-state resistance (240Ohm), supply voltage ranges (3V ~ 20V single, ±2.5V ~ 9V dual), bandwidth (30MHz), and operating temperature range (-55°C ~ 125°C). The packaging format difference (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect circuit performance.
Q: What is the primary advantage of using 74HC4053D,653 or MC74HC4053ADG over CD4053BMT?
A: These parts offer significantly lower on-state resistance (120Ohm and 100Ohm respectively) compared to CD4053BMT (240Ohm). Lower on-state resistance reduces signal attenuation, improves bandwidth performance (170MHz and 120MHz respectively), and decreases power dissipation. However, they operate within narrower supply voltage ranges and may have different temperature specifications. Application-specific voltage and temperature requirements must be verified before substitution.
Q: Can MC74LVX4053DR2G replace CD4053BMT in a design requiring ±2.5V ~ ±9V dual supply operation?
A: No. MC74LVX4053DR2G supports only ±3V dual supply operation, which does not encompass the full ±2.5V ~ ±9V range required by CD4053BMT. This part is suitable only for applications operating at exactly ±3V dual supply. Additionally, its supply voltage range (2.5V ~ 6V single supply) is narrower than CD4053BMT.
Q: Are all substitute parts available in 16-SOIC package?
A: Yes. All substitute parts listed are housed in 16-SOIC (0.154", 3.90mm Width) surface mount packages, ensuring mechanical and electrical compatibility with CD4053BMT PCB layouts.
Q: What is the impact of using MC14053BDG, which does not support dual supply operation?
A: MC14053BDG is suitable only for applications using single supply voltage (3V ~ 18V). If the design requires dual supply operation (±2.5V ~ ±9V), MC14053BDG cannot be used. Verify application power supply architecture before selecting this substitute.
Q: Does HEF4053BT,653 have any performance limitations compared to CD4053BMT?
A: HEF4053BT,653 exhibits three limitations: (1) higher leakage current (200nA versus 100nA), (2) reduced bandwidth (70MHz versus 30MHz, though this is an improvement), and (3) no dual supply support. The higher leakage current may impact low-power applications. Verify leakage current specifications against application requirements.
Q: Can 74HCT4053D,118 be used in applications requiring wide supply voltage range?
A: No. 74HCT4053D,118 is restricted to 4.5V ~ 5.5V single supply operation, making it suitable only for TTL-compatible designs with this specific voltage requirement. It cannot replace CD4053BMT in applications requiring 3V ~ 20V supply range flexibility.
Q: What is the difference between MC74HC4053ADG and MC74HC4053ADR2G?
A: Both parts are electrically identical with 100Ohm on-state resistance, 120MHz bandwidth, and -55°C ~ 125°C operating temperature. The difference is packaging format: MC74HC4053ADG is supplied in Tube packaging, while MC74HC4053ADR2G is supplied in Tape & Reel (TR) format. Select based on procurement and assembly requirements.
