UPD4702 Datasheet Incremental Encoder 8-bit Up/down Counter CMOS Integrated Circuits

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD4702 INCREMENTAL ENCODER 8-BIT UP/DOWN COUNTER CMOS INTEGRATED.

General Description

The µPD4702 is 8-bit up/down counters for an incremental encoder.

Two-phase (A, B) incremental input signals are phase-differentiated, and on each signal edge, an up-count is executed if the A phase is leading, or a down-count if the B phase is leading.

Eight-bit count data is output in real time.

Key Features

  • Incremental inputs (A, B).
  • On-chip phase discrimination circuit (up-count mode when the phase order is A → B, down-count mode when B → A) 4-multiplication count method.
  • On-chip edge detection circuit.
  • 8-bit up/down counter latch output o Carry output, borrow output.
  • Count data output controllable (3-state output).
  • CMOS, single +5 V power supply PIN.
