U74HC157

DESCRIPTION 

The U74HC157 is a quadruple 2-line to 1-line data 

selectors/multiplexers. When G is high all outputs are low. When 

G is low a 4-bit word is selected from one of two sources and is 

routed to the four outputs. The device provides true data. 

FEATURES 

* Wide supply voltage range from 2V to 6V 

* Typical tPD at 11ns from A or B to Y at 6V, CL=50pF 

* Low power consumption, ICC = 8 μA (MAX) at 6V 

* ±6 mA output driver at 5V 

* Low Input Current of 0.1uA Max
