CD4059A

The CD4059A types are divide-by-N down-counters that can be programmed to divide an input frequency by an number"N" from 3 to 15,999.The output signal is a pulse one clock-cycle wide occuring at a rate equal to the input frequency divided by N.This single output has TTL drive capability.The down-counter is preset by means of 16 jam inputs.

Features of of the CD4059A are:(1)Presettable down-counter; (2)fully static operation; (3)master preset initialization; (4)quiescent current specified to 15 volts; (5)1 volt noise margin, full package temperature range; (6)5 V and 10 V parametric ratings.

The absolute maximum ratings of the CD4059A can be summarized as:(1): DC supply-voltage range(VDD) is -0.5 V to +15 V(voltages referenced to Vss terminal); (2): input voltage range, all inputs is -0.5 V to VDD+0.5 V; (3): operating temperature range(Ta) is -55 to +125; (4): storage temperature range(Tstg) is -65 to +150.
