Description

The µPD4704 is 8-bit up/down counters for extension of the µPD4702 incremental encoder counter. They performan up/down-count using an 8-bit width with a µPD4702 carry or borrow signal as input. In addition, a carry outputandborrow output are also provided for further extension of the count width, enabling extension to be performedin 8-bit units.
