General Description

The MM5369 is a CMOS integrated circuit with 17 binary divider stages that can be used to generate a precise reference from commonly available high frequency quartz crystals. An internal pulse is generated by mask programming the combinations of stages 1 through 4, 16 and 17 to set or reset the individual stages. The MM5369 is advanced one count on the positive transition of each clock pulse. Two buffered outputs are available: the cyrstal frequency for tuning purposes and the 17th stage output. The MM5369 is available in an 8-lead dual-in-line epoxy package.

This part has been obsoleted by the manufacturer. (National Semiconductor) It is not intended for new designs. Perfect replacement part for repairs or experimentation. It uses a colorburst crystal ( 3.579545 MHz) and provides an acurate 60 Hz timebase. Used in clocks and other time based equipment.

This product contains lead. They have all been tested and all provided 60.00 Hz
