Multiplexer/Demultiplexer configuration: 1:1
Package type: 14-TSSOP surface mount
Supply voltage compatibility: Minimum 2V ~ 10V overlap required
On-state resistance: Must not exceed application requirements

Substitute parts are grouped into three categories based on on-state resistance performance:

Category 1: Direct Resistance Match (95Ohm) — 74HC4066PW,118 and 74HC4066PW-Q100,11 from Nexperia USA Inc. provide improved performance with lower on-state resistance while maintaining the same 14-TSSOP package and SPST-NO configuration. These parts are active products with enhanced bandwidth (200MHz vs. 20MHz) and faster switching times.

Category 2: Ultra-Low Resistance (4.5Ohm) — MAX4737EUD+, MAX4737EUD+T, MAX4747EUD+, and MAX4747EUD+T from Analog Devices Inc./Maxim Integrated offer significantly lower on-state resistance for applications requiring minimal signal attenuation. These parts operate at 1.8V ~ 5.5V (MAX4737 series) or 2V ~ 11V (MAX4747 series) and feature superior bandwidth and crosstalk performance.

Category 3: Complementary Switch Configuration (4.5Ohm, SPST-NC) — MAX4738EUD+ and MAX4738EUD+T provide normally-closed switch functionality with the same ultra-low resistance characteristics as the MAX4737 series, suitable for applications requiring inverted logic control.

Category 4: Mixed Switch Configuration (25Ohm, SPST-NO/NC) — MAX4749EUD+ and MAX4749EUD+T combine normally-open and normally-closed switch functions in a single package with 25Ohm on-state resistance, offering design flexibility for complex switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 74HC4066PW,118 directly replace the CD74HC4016PWR? A: Yes, with design verification. Both parts feature SPST-NO switch configuration, 4-circuit architecture, and identical 14-TSSOP packaging. The 74HC4066PW,118 operates within the same 2V ~ 10V supply range and maintains functional compatibility. The lower on-state resistance (95Ohm vs. 170Ohm) and higher bandwidth (200MHz vs. 20MHz) represent performance improvements. Operating temperature range differs (-40°C ~ 125°C vs. -55°C ~ 125°C), which must be evaluated for your application's minimum temperature requirement.

Q: What is the difference between 74HC4066PW,118 and 74HC4066PW-Q100,11? A: Both parts are electrically identical with the same on-state resistance, bandwidth, and switching characteristics. The 74HC4066PW-Q100,11 includes AEC-Q100 automotive qualification and is supplied in Tape & Reel packaging, while the 74HC4066PW,118 is supplied in Cut Tape & Digi-Reel format. Select the AEC-Q100 variant for automotive applications requiring formal qualification documentation.

Q: Why do MAX4737 and MAX4747 parts have different supply voltage ranges? A: The MAX4737EUD+/MAX4737EUD+T operate at 1.8V ~ 5.5V, while MAX4747EUD+/MAX4747EUD+T operate at 2V ~ 11V. The MAX4747 series accommodates higher supply voltages, making it suitable for applications requiring extended voltage headroom. Select based on your system's power supply specifications.

Q: Can I use MAX4738 (SPST-NC) in place of CD74HC4016PWR (SPST-NO)? A: No, not without circuit modification. The MAX4738 provides normally-closed switch functionality, meaning the switch conducts when control logic is low. The CD74HC4016PWR provides normally-open functionality, conducting when control logic is high. Using MAX4738 requires inverting the control signal or redesigning the switching logic.

Q: What is the significance of the "+T" suffix in part numbers like MAX4737EUD+T? A: The "+T" suffix indicates Tape & Reel packaging, suitable for automated assembly processes. Parts without this suffix (e.g., MAX4737EUD+) are supplied in Tube packaging. Both variants are electrically identical; packaging selection depends on your manufacturing process requirements.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all substitute parts listed maintain ROHS3 compliance and MSL-1 moisture sensitivity rating, ensuring compatibility with standard manufacturing practices and environmental regulations.

Q: Which substitute part offers the lowest on-state resistance? A: The MAX4737EUD+, MAX4737EUD+T, MAX4738EUD+, and MAX4738EUD+T all provide 4.5Ohm on-state resistance, the lowest among all listed substitutes. These parts are suitable for applications requiring minimal signal attenuation and superior bandwidth performance.

Q: Can MAX4749 (SPST-NO/NC) replace CD74HC4016PWR? A: Yes, functionally. The MAX4749EUD+ and MAX4749EUD+T provide SPST-NO/NC mixed configuration with 25Ohm on-state resistance and 250MHz bandwidth. These parts offer additional design flexibility by combining normally-open and normally-closed switch functions. Supply voltage range extends to 2V ~ 11V, accommodating broader power specifications than the original part.
