CD4059AE

The CD4059AE  belongs to the CD4059A series. It is a kind of CMOS programmmable divide-by-'N' counter that can be programmed to divide an input frequency by any number 'N' from 3 to 15,999. It can be used in many occasions such as communications digital frequency,fixed or programmable frequency division,'Time Out' timer for consumer-application industrial controls and companion application note ICAN-6374.

There are CD4059AE features as follows. (1) synchronous programmable; (2) presettable down-counter; (3) fully static operation; (4) mode-select control of initial decade counting function; (5) master preset initialization; (6) 1 volt noise margin,full package temperature range; (7) 5 V to 10 V parametric ratings.

What comes next is the description about CD4059AE absolute maximum ratings. (1): DC supply voltage (VDD) ranges from -0.5 V to 15 V; (2): input voltage is from -0.5 V to VDD+0.5 V; (3): power dissipation per package is 500 mW when TA is from -55 to 100 and derate linearly to 100 mW when TA is from 100 to 125 ; (4): device dissipation per output transistor is 100 mW; (5): operating temperature is from -55 to 125 ; (6): storage temperature ranges from -65 to 150 . Then is its operating ratings at TA is 25 . (1): CD4059AE supply voltage is from 3 V to 12 V; (2): CD4059AE minimum clock pulse is 200 ns when VDD is 5 V; (3): the maximum clock input frequency is 1.5 MHz at VDD is 5 V and is 3 MHz when VDD is 10 V; (4): clock input rise time is 15 s at VDD is 5 V and is 5 s at VDD is 10 V.
