LSI Computer Systems RDD104
The RDD104 is a monolithic CMOS four decade divider circuit that advances on each negative transition of the input clock pulse. When the reset input is high the circuit is cleared to zero. The clock input is applied to a three stage inverting amplifier network whose output is brought out so that an external crystal network can be used to form an oscillator circuit.| Part No. | RDD104 |

DESCRIPTION
OF OPERATION: If the clock output is not used,the amplifier acts as an input buffer. Two select inputs are provided which enables the circuit to divide by 10, 100, 1,000 or 10,000. FIGURE 1MAXIMUM RATINGS
