Metal may be exposed on the top or bottom of this product.
This will not affect any quality, reliability or electrical spec.
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.
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.
ST
pin (SCE)
ST
pin = "H" or "open" : Specified frequency output.
ST
pin = "L" : Output is low level ,oscillation stops.
To maintain stable operation, provide by-pass capacitor with
more than 0.1
μF
at a location as near as possible to the power
source terminal of the crystal products (between V
CC
- GND).
