UPD4702 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 outp

UPD4702 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. A.
