Remarks 1. The µPD3739 can be operated leaving pin 2 (NC) unconnected, and connecting pin 4 (NC) and pin 11
(NC) to a +12 V power supply (when replaces the µPD35H71A).
2. It is recommended that pins 6 (φ2L1) and 17 (φ1L2) each is separately driven a driver other than that
of pins 10, 13 (φ11, φ12) and pins 9, 14 (φ21, φ22).
3. The inverters shown in the above application circuit example are the 74AC04.
