DescriptionThe SN74HC161NSRE4 devices are 4-bit binary counters.Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable input and internal gating.
Features of the SN74HC161NSRE4 are:(1)wide operating voltage range of 2V to 6V;(2)output can drive up to 10 LSTTL loads;(3)low power consumption 80-A Max ICC;(4)typical tpd=14ns;(5)±4-mA output drive at 5V;(6)low input current of 1;(7)ESD protection exceeds JESD 22A Max;(8)internal look-ahead for fast counting;(9)carry output for n-bit cascading;(10)synchronous counting;(11)synchronousty programmable.
The absolute maximum ratings of the SN74HC161NSRE4 can be summarized as:(1):the parameter is supply voltage range,the symbol is VCC,the rating is -0.5 to 7,the unit is V;(2):the parameter is voltage input clamp current,the symbol is IIK,the rating is ±20,the unit is mA;(3):the parameter is output clamp current,the symbol is IOK,the rating is ±20,the unit is mA;(4):the parameter is continuous output current,the symbol is IO,the rating is ±25,the unit is mA;(5):the parameter is continuous current through,the symbol is VCC to GND,the rating is ±50,the unit is mA;(6):the parameter is package thermal impedance NS package,the symbol is JA,the rating is 64,the unit is /W;(7):the parameter is storage temperature range,the symbol is Tstg,the rating is -65 to 150,the unit is
