Product Summary

The CD4040 is a ripple-carry binary counter. The applications of the CD4040 include control counters, frequency dividers, timers and time-delay circuits. The couter stage is master-slave flip-flop. The state of a counter advances one count on the negative transition of each input pulse.

Parametrics

CD4040 absolute maximum ratings: (1)DC supply voltage range, VDD: -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; (5)device dissipation per output transistor: 100mW; (6)operating temeprature range, TA: -55 to 125℃; (7)storage temperature range, Tstg: -55 to 150℃; (8)lead temperature: 265℃.

Features

CD4040 features: (1)medium speed operation; (2)fully static operation; (3)buffered inputs and outputs; (4)100% tested for quiescent current at 20V; (5)standardized, symmetrical output characteristics; (6)fully static operation; (7)common reset; (8)5V, 10V and 15V parametric ratings; (9)maximum input current of 1μA at 18V over full package temeprature range; (10)noise margin.
