Engineering Selection Recommendations
For Direct Electrical Compatibility (74HCT Logic Family):
CD74HCT4053PWR is the primary recommended substitute. This part maintains identical supply voltage specifications (4.5V ~ 5.5V single, ±1V ~ 5V dual) and comparable on-state resistance (130Ohm vs. 120Ohm), with Active product status ensuring long-term availability. The package change from 16-SSOP to 16-TSSOP requires PCB layout modification but provides superior electrical performance with 200MHz bandwidth versus 170MHz. All RoHS3 compliance and MSL specifications are maintained.
CD74HCT4053PWT provides equivalent electrical performance with Last Time Buy status, suitable for designs where supply continuity is not critical. CD74HCT4053PWRE4 is classified as Obsolete and should be avoided for new designs.
For Extended Supply Voltage Range (CMOS Logic Family):
CD4053BPWR is recommended for applications requiring expanded supply voltage capability (3V ~ 20V single, ±2.5V ~ 9V dual). This part is Active status with substantial inventory availability. The trade-off is higher on-state resistance (240Ohm vs. 120Ohm) and reduced bandwidth (30MHz vs. 170MHz), which may impact signal integrity in high-frequency applications. This substitution is appropriate only when the expanded voltage range is a design requirement.
CD4053BPW and CD4053BPWRG4 provide equivalent electrical specifications to CD4053BPWR with Last Time Buy and Obsolete status respectively, and should not be selected for new designs.
Package Consideration:
All substitute parts use 16-TSSOP packaging (0.173" width) versus the original 16-SSOP (0.209" width). PCB layout redesign is required. The TSSOP package is narrower and may provide improved board density in space-constrained applications.
Frequently Asked Questions (FAQ)
Q: Can CD74HCT4053PWR be used as a direct replacement for 74HCT4053DB,112 without circuit modification?
A: CD74HCT4053PWR is electrically compatible with identical supply voltage specifications and comparable on-state resistance. However, PCB layout modification is required due to package format change from 16-SSOP to 16-TSSOP. The footprint dimensions differ (0.209" vs. 0.173" width), necessitating new PCB artwork. No circuit schematic changes are required.
Q: What is the difference between the 74HCT4053 and CD4053 series substitutes?
A: The 74HCT4053 series (HCT logic family) maintains the original supply voltage specifications (4.5V ~ 5.5V single, ±1V ~ 5V dual) with lower on-state resistance (130Ohm) and higher bandwidth (200MHz). The CD4053 series (CMOS logic family) offers expanded supply voltage range (3V ~ 20V single, ±2.5V ~ 9V dual) with higher on-state resistance (240Ohm) and lower bandwidth (30MHz). Select based on your circuit's voltage requirements and signal frequency characteristics.
Q: Is the on-state resistance difference between 120Ohm and 130Ohm significant?
A: The 10Ohm difference (8.3% increase) between 74HCT4053DB,112 (120Ohm) and CD74HCT4053PWR (130Ohm) is within typical analog switch tolerance and acceptable for most applications. Applications with critical impedance matching or very low signal levels should evaluate the impact on signal attenuation and noise performance.
Q: Why do all substitute parts have -55°C minimum operating temperature versus -40°C for the original?
A: The substitute parts from Texas Instruments specify -55°C to 125°C operating range, which is an extended specification compared to the original -40°C to 125°C. This represents improved performance and wider applicability, not a limitation. Designs requiring only -40°C minimum operation are fully supported.
Q: Can CD4053BPWR be used in a 5V single supply circuit?
A: Yes. CD4053BPWR supports 3V ~ 20V single supply voltage range, which includes 5V operation. However, verify that the higher on-state resistance (240Ohm vs. 120Ohm) and lower bandwidth (30MHz vs. 170MHz) are acceptable for your signal routing application. The expanded voltage range is the primary advantage of this substitute.
Q: What is the impact of package change from 16-SSOP to 16-TSSOP?
A: The 16-TSSOP package is narrower (0.173" vs. 0.209" width) and requires new PCB footprint design. Pin pitch and lead count remain identical. The narrower package may provide improved board layout density. Electrical performance is not affected by the package format change.
Q: Which substitute part should I select for a new design?
A: For new designs, select CD74HCT4053PWR (Active status) if your circuit operates at 4.5V ~ 5.5V single supply or ±1V ~ 5V dual supply. If your design requires extended voltage range (3V ~ 20V), select CD4053BPWR (Active status). Avoid parts with Last Time Buy or Obsolete status for new production designs.
