CD74HC4046A: Replacing HEF4046B with CD74HC4046A or SN74LV4046A

Part Number: CD74HC4046A
Other Parts Discussed in Thread: SN74LV4046A, CD4046B

Hi team,

I'm looking to replace the HEF4046B with either the CD74HC4046A or SN74LV4046A. They seem to be pin-to-pin options, but there's a difference with regards to pin 15. On the Nexperia device pin 15 is a Zener diode input for a regulated supply and on the TI devices it is a phase comparator output.

Would there be any risk with dropping in either TI device in place of the Nexperia part? Any suggestions to protect the circuit?
