UPD4704 Datasheet Extension 8-bit Up/down Counter CMOS Integrated Circuits

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD4704 EXTENSION 8-BIT UP/DOWN COUNTER CMOS INTEGRATED.

General 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.

Key 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 PIN NAMES Up Down Reset STB OE CD0-7 Carry : Up-count input : Down-count input : Counter reset input : Latch strobe signal input : Output control signal input : Count data outputs : Carry pulse output PIN.
