Hi team
Could you help to check what is the output status of CD74HC4053 when the device is disabled(When EN is High), is it tri-state status?

Alex,
The output status of passive FET switches like the CD74HC4053 will be high impedance when the FET is disabled. You can see this Hi-Z spec stated in the datasheet by the off state leakage current. Even with a signal Vis as high as Vcc no more than 1uA will pass through the switch.
Vcc= IRoff
5 V = (1uA) Roff
5V/(1uA) = 5M ohm = Hi -Z = Roff
Thank you,
Adam
