The metal case inside of the molding compound may be exposed on the top or  
bottom of this product. This purely cosmetic and does not have any effect on  
quality, reliability or electrical specs.  
Note.  
OE pin (PTF,PCE,PDE,PTW,PHW,PCW,PTG,PHG,PCG)  
OE pin = "H" or "open" : Specified frequency output.  
OE pin = "L" : Output is high impedance.  
5.08  
ST pin (STW, SHW, SCW,SCG)  
ST pin = "H" or "open" : Specified frequency output.  
ST pin = "L" : Output is low level (weak pull - down),oscillation stops.  
To maintain stable operation, provide a 0.01uF to  
0.1uF by-pass capacitor at a location as near as  
possible to the power source terminal of the crystal  
product (between Vcc - GND).  
ST pin (SCE)  
ST pin = "H" or "open" : Specified frequency output.  
ST pin = "L" : Output is low level ,oscillation stops.
