MOTOROLA SEMICONDUCTOR TECHNICAL DATA Phase Comparator and Programmable Counters The MC14568B consists of a phase comparator, a divide­by­4, 16, 64 or 100 counter and a programmable divide­by­N 4­bit binary counter (all positive­edge triggered) constructed with MOS P­channel and N­channel enhancement mode devices (complementary MOS) in a monolithic structure. The MC14568B has been designed for use in conjunction with a programmable divide­by­N counter for frequency synthesizers and phase­ locked loop applications requiring low power dissipation and/or high noise immunity. This device can be used with both counters cascaded and the output of the second counter connected to the phase comparator (CTL high), or used independently of the programmable divide­by­N counter, for example cascaded with a MC14569B, MC14522B or MC14526B (CTL low). · Supply Voltage Range = 3.0 to 18 V · Capable of Driving Two Low­Power TTL Loads, One Low­Power Schottky TTL Load or Two HTL Loads Over the Rated Temperature Range. · Chip Complexity: 549 FETs or 137 Equivalent Gates MAXIMUM RATINGS* (Voltages referenced to VSS) Rating Symbol VDD Vin Iin PD TA Tstg DC Supply Voltage Value MC14568B L SUFFIX CERAMIC CASE 620 P SUFFIX PLASTIC CASE 648 D SUFFIX SOIC CASE 751B ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBD Plastic Ceramic SOIC ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Unit Vdc Vdc ­ 0.5 to + 18 ± 10 500 ­ 55 to + 125 ­ 65 to + 150 Input Voltage, All Inputs ­ 0.5 to VDD + 0.5 DC Input Current, per Pin Power Dissipation, per Package Operating Temperature Range Storage Temperature Range mAdc mW TA = ­ 55° to 125°C for all packages.
