Product name (Standard form)

External dimensions


(Unit: mm)

OE Pin (PT, PH, PC)
OE Pin = "H" or "open": Specified frequency output.
OE Pin = "L": Output is high impedance.
ST Pin (ST, SH, SC)
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).
