UPD4704 - EXTENSION 8-BIT UP/DOWN COUNTER CMOS INTEGRATED CIRCUITS

The µPD4704 is 8-bit up/down counters for extension of the µPD4702 incremental encoder counter.

They perform an up/down-count using an 8-bit width with a µPD4702 carry or borrow signal as input.

In addition, a carry output and borrow output are also provided for further extension of the count width,
