UPD4701A Datasheet Mos Integrated Circuit

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD4701A INCREMENTAL ENCODER.

General Description

The µPD4701A is a counter for an X, Y 2-axis incremental encoder.

When a two-phase encoder signal is input for the X and Y axes, direction discrimination and putation is performed, and count data is output in 8-bit parallel form.

In addition, a 3-contact-point input buffer is incorporated, which is useful for applications which use a pointing device such as a mouse or track-ball.

Key Features

  • X, Y 2-axis incremental encoder counter.
  • Counter input (Schmitt-triggered input) X axis: XA, XB 2-phase signal   4-multiplication count method used Y axis: YA, YB 2-phase signal .
  • Counters: 12-bit binary up/down counters (2 sets, X & Y) Reset value: 000H.
  • Count data output: 8-bit parallel latch output × 2 (including key input flag).
  • On-chip 3-contact-point key input buffer circuit.
  • CMOS.
  • Single +5 V power supply PIN.
