CD4040 - 12-Stage Ripple Carry Binary Counter IC
CD4040 - 12-Stage Ripple Carry Binary Counter IC The CD4x Series CD4040 is a ripple-carry binary counter that features 12 stages, push-pull type, and balanced outputs, with standard speed (TPD > 50ns). All counter stages are master-slave flip-flops. Supports wide input voltage ranges from 3V to 18V. The maximum input current at 18V is 1 uA whereas 100 nA at 18V and 25°C. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all-zeros state. Schmitt's trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered. 16 Pin DIP is available in a hermetic dual-in-line ceramic package. We also have a CD4020 with similar features. The differences are CD4020 is a 14 Stage binary counter whereas CD4040 is a 12 Stage binary counter and there is a difference between the pin layout. check out : CD4518 - Dual BCD Up Counter IC (Original) Pinout: Pinout of CD4040 IC Applications: Control Counters Timers Frequency Dividers Time-Delay Circuits Package Includes: Selected qty of IC - CD4040 Specifications: VCC (Min) 3V VCC (Max) 18V Bits (#) 12 Voltage (Nom) 5V, 10V, and 15V F at nom voltage (Max) 8MHz ICC at nom voltage (Max) 0.03mA tpd at nom Voltage (Max)(ns) 160ns IOL (Max) 1.5mA IOH (Max) -1.5mA Function Counter Type Binary Operating temperature range (C) -55 to 125
