标题: New Logic Test - 4020 Vector Table [打印本页]

作者: yovish 时间: 2021-5-23 21:57 标题: New Logic Test - 4020 Vector Table

Enclosed is the new layout to be added to the logic tests.
The test was performed on the CD4020BE (CMOS 14-Stage Ripple-Carry Binary Counter/Divider) chip from Texas Instruments.

P.S.
4020 is a 14-bit counter, so it counts up to 16383 (2 ^ 14-1). To check this counter well, it would be nice to add a multiple pulse. There are more integrated circuits that would be easier to test in this way.

In the 4020 IC, I could only overload a small part of the functionality because I hit the limit of the number of lines (512) in the logic vector!
