UPD4704

EXTENSION 8Bit UP/DOWN COUNTER CMOS INTEGRATED CIRCUITS

DESCRIPTION

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, enabling extension to be performed in 8-bit units.

FEATURES

• 8-bit up/down counter for extension of µPD4702

• Count data output controllable latch and 3-state output

• Extension carry and borrow outputs

• CMOS, single +5 V power supply
