8 Select 1 Analog switch chip.
hef4081 is an 8-select 1 analog switch chip produced by nexperia Electronics, with three select switches (S1, S2, S3), an enable pin (E), eight independent input\/output switches (Y0~Y7), and a common input\/output switch (Z), the working principle is as follows:
When the Enable pin E is high, the switch is off regardless of the status of the selection pins (S1~S3).
It's a dual-core high-frequency chip.
