I saw the reply, but let's get a little more exact, here. Pin 1: has a dot; no connection Pin 7: ground Pin 8: output, typically square wave, rail-to-rail Pin 14: power, +5.0VDC (VCC) There are also half-size oscillators, in an 8-pin-DIP sized package. Same sort of layout, just shorter. Pin 1: dot, no connection Pin 4: ground Pin 5: output Pin 8: power Power and ground are laid out just like on standard logic parts; lower left corner is ground, upper right corner is power, with the part oriented pin 1 toward the top. forbesm@peak.org KC7LZD Mark G.
