Product Summary
The CD4020 is a CMOS ripple-carry binary counter/divider. All counter stages are master-slave flip-flops. he state of a counter advances one count on teh negative transition of each inputs pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered. The applications of the CD4020 include control counter, frequency dividers, timers and time-delay circuits.
Parametrics
CD4020 absolute maximum ratings: (1)DC supply voltage range, VDSD: -0.5 to 20V; (2)input voltage range, all inputs: -0.5 to VDD+0.5V; (3)DC input current, any one input: ±10mA; (4)power dissipation per package, PD: 500mW for TA=-55 to 100℃; (5)device dissipation per output transistor: 100mW; (6)operating temperature range, TA: -55 to 125℃; (7)storage tmperature range, Tstg: -65 to 150℃; (8)lead temperature: 250℃.
