DESCRIPTION

The use of integrated circuit techniques allows the M991 to incorporate the control, tone generating, and power output buffer into a single 14-pin DIP or a 16-pin SOIC. A 3.58-MHz (color burst) crystal-controlled time base guarantees accuracy and repeatability. Ordering Information Part # M-991 M-991-01SM M-991-01SMTR M-991-02SM M-991-02SMTR
