DESCRIPTION
The
μ
PD4704 is 8-bit up/down counters for extension of the
μ
PD4702 incremental encoder counter. They perform
an up/down-count using an 8-bit width with a
μ
PD4702 carry or borrow signal as input. In addition, a carry output
and borrow output are also provided for further extension of the count width, enabling extension to be performed
in 8-bit units.
FEATURES
8-bit up/down counter for extension of
μ
PD4702
Count data output controllable (latch and 3-state output)
Extension carry and borrow outputs
CMOS, single +5 V power supply
