(1) The diagram is for 5 V application. For 3.4 V
application an additional resistor of 150 kΩ should be
connected between pin 18 and ground.
(2) For crystal oscillator circuit see Figs 3 and 4.
(3) For single and double-speed applications a 1 kΩ
resistor should be used. For single-speed only
applications a 2.2 kΩ resistor should be used
(4) The connections to TDA1300 are shown for single
Foucault mechanisms.
