EM20035
3 SEC. VOICE SYNTHESIZER IC.
4.12.1996
E). Pulldown Resistor
To prevent noise interference and to provide CdS trigger interface, the TR pins of EM20035 provide
shifting pulldown resistor. The shifting resistor is dependent on the level of TR pin
TR pin tied to : V
DD
: R= 1 M ohm
TR pin tied to : V
SS
: R= 270 K ohm
