The chip contains a crystal controlled oscillator, a divide-by- three counter and complete “Ready” synchronization and reset logic. Static CMOS circuit design permits operation with an external fre- quency source from DC to 25MHz. Crystal controlled operation to 25MHz is guaranteed with the use of a parallel, fundamental mode crystal and two small load capacitors. All inputs (except X1 and RES) are TTL compatible over tempera- ture and voltage ranges. Power consumption is a fraction of that of the equivalent bipolar cir- cuits. This speed-power characteristic of CMOS permits the designer to custom tailor his system design with respect to power and/or speed requirements. Ordering Information PART NUMBER TEMP.
