Beers 4029 Presettable Counter

Classic CMOS presettable up/down counter IC in eurorack form.

The rising edge of a signal on CLOCK increases or decreases the binary number available on outputs Q1Q2Q3, and Q4 depending on what's present on the DN/UP input:

Low (≤0.5V) counts UP,

High (≥0.5V) counts DOWN.

(Maybe this would have been more intuitive the other way around?)

R21 on the PCB supplies the switch contact of the DN/UP jack with +ve voltage so the counter is in DOWN mode with nothing plugged in. Remove/omit R21 to make UP the default direction.

 

A positive signal on PRE EN will ignore any clock pulses and replace the current binary count with whatever data is present on the 'Jam' inputs J1, J2, J3, J4.

With nothing plugged in this will be 0000, otherwise any signals you plug in will be converted to a binary on/off state and will be passed to their respective outputs while PRE EN is high.

Sending a short trigger to PRE EN while you have various signals plugged into J1-4 works as a data latch.

 

I haven't used the binary/decade, carry in, or carry out pins of the 4029 in this version. (booo)
