Procurement Notes
Verify the specific ordering suffix '112' against the manufacturer's current catalog to confirm packaging details and availability status. Ensure the component meets RoHS compliance requirements for the intended market. Confirm that the SO16 package variant aligns with PCB layout constraints. Check for any recent product change notices or end-of-life announcements directly from NXP Semiconductors before finalizing procurement plans.
Selection Notes
Select this component when dual independent 3-channel switching is required with shared control logic. Consider the ON resistance variation based on input voltage levels for precision analog paths. Verify that the supply voltage range (5 V to 15 V) matches the system design. Ensure the Schmitt-trigger inputs are utilized to handle noisy digital control lines effectively in industrial environments.
Part Context
The HEF4952B series belongs to NXP's standard CMOS logic family, designed for general-purpose analog and digital switching. It complements other multiplexer variants like the HEF4052 by offering a specific 3-channel configuration with additional supplementary switches. This part is widely used in legacy and modern industrial designs requiring robust analog signal routing.
Replacement Considerations
Check for direct pin-compatible alternatives such as the HEF4952BTT-Q100 if automotive qualification is needed. Verify functional equivalence regarding ON resistance and leakage currents when substituting with generic CMOS analog switches. Ensure the replacement supports the same SO16 package dimensions.
