MC14569B Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14569B Programmable Divide-By-N Dual 4-Bit Binary/BCD Down Counter The MC14569B is a programmable divide- by- N dual 4- bit binary or BCD down counter constructed with MOS P- channel and N- channel enhancement mode devices (plementary MOS) in a monolithic structure. This device has been designed for use with the MC14568B phase parator/counter in frequency synthesizers, phase- locked loops, and other frequency division applications requiring low power dissipation and/or high noise immunity. - Speed- up Circuitry for Zero Detection - Each 4- Bit Counter Can Divide Independently in BCD or Binary Mode - Can be Cascaded With MC14568B, MC14522B or MC14526B for Frequency Synthesizer Applications - All Outputs are Buffered - Schmitt Triggered Clock Conditioning MAXIMUM RATINGS- (Voltages Referenced to VSS) Symbol VDD Parameter DC Supply Voltage L SUFFIX CERAMIC CASE 620 P SUFFIX PLASTIC CASE 648 DW SUFFIX SOIC CASE 751G ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBDW Plastic Ceramic SOIC ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Value Unit V V m A m W - 0.5 to + 18.0 Vin, Vout Iin, Iout PD Tstg TL Input or Output Voltage (DC or Transient) Input or Output Current (DC or Transient), per Pin Power Dissipation, per Package† Storage Temperature Lead Temperature (8- Second Soldering) - 0.5 to VDD + 0.5 ± 10 500 - 65 to + 150 260 TA = - 55° to 125°C for all packages. _C _C - Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: - 7.0 m W/_C From 65_C To 125_C Ceramic “L” Packages: - 12 m W/_C From 100_C To 125_C BLOCK DIAGRAM P0 P1 P2 P3 CTL = Low for Binary Count CTL = High for BCD Count 3 4 5 6 CTL1 CTL2 2 10 P4 P5 P6 P7 11 12 13 14 VDD = PIN 16 VSS = PIN 8 15 CLOCK BINARY/BCD COUNTER #1 CLOCK LOAD BINARY/BCD COUNTER #2 CASCADE 7 FEEDBACK ZERO DETECT ENCODER 1 ZERO DETECT REV 3 1/94 ©MOTOROLA...
