Are these about the same as crystal oscillators, in interfacing, that are of standard HC49 and tuning fork cases? Or are they stand alone components that just require a buffer/driver and no external matching capacitors to help reach desired frequency?
They've just the 4 pins for 5V, 0V and Out, 4th NC. Ones at Rapid (UK) will drive 10 TTL, so I guess the buffer is included too. Full can=fit 14-pin DIL socket, Half can=8-pin socket. hth.
