Hi,
Customers want to check the impedance of each pin.
However, because the data sheet is old, the description of each pin and I/O information are not described.
https://www.ti.com/lit/ds/symlink/cd4046b.pdf
Could you tell me the pin description and I/O information?
Pin | Name | Discription | I/O |
1 | Phase Pulses | ||
2 | Phase Comparator I Out | ||
3 | Comparator IN | ||
4 | Vco Out | ||
5 | Inhibit | ||
6 | CI 1 | ||
7 | CI 2 | ||
8 | Vss | ||
9 | Vco In | ||
10 | Phase Pulses | ||
11 | R1 to Vss | ||
12 | R2 to Vss | ||
13 | Phase Comparator II Out | ||
14 | Signal In | ||
15 | Zener | ||
16 | Vdd |
Best regards,
Yusuke
Hey Yusuke,
Here is a more recent datasheet for the 4046 function that has the details you are looking for. The arrows in the image you show also indicate whether its and input or output.
