Order this document by 253/ The 253 is a super low power 64/65, 2/29 dual modulus prescaler. Motorola s advanced ipolar MOSI V technology is utilized to achieve low power dissipation of 4.3 mw at a minimum supply voltage of 2.7 V. The ivide Ratio ontrol input, SW, permits selection of divide ratio as desired. HIGH on SW selects 64/65; an OPEN on SW selects 2/29. The Modulus ontrol input,, selects the proper divide number after SW has been biased to select the desired divide ratio. Standby mode is featured to reduce current drain to 5 µ typical at 2.7 V when the standby pin, S, is switched LOW, disabling the prescaler. Onchip output termination provides 5 µ (typical) output current, which is sufficient to drive a MOS synthesizer input high impedance load (. pf typical)..
