DescriptionThe SN74ALS139NSRE4 are dual 2-line to 4-line decoders/demultiplexers designed for use in high-performance memory-decoding or data-routing applications requiring very short propagation delay times.In high-performance memory systems,these devices can minimize the effects of system decoding.When employed with high-speed memories utilzing a fast-enable circuit,the delay times of these decoders and the enable time of the memory are usually less than the typical access time of the memory.
Features of the SN74ALS139NSRE4 are:(1)designed specifically for high-speed memory decoders and data transmission systems;(2)incorporate two enable inputs to simplify cascading and/or data reception;(3)package options include plastic.
The absolute maximum ratings of the SN74ALS139NSRE4 can be summarized as:(1):the parameter is supply voltage range,the symbol is VCC,the rating is 7,the unit is V;(2):the parameter is input voltage,the symbol is VI,the rating is 7,the unit is V;(3):the parameter is operating free-air temperature range,the symbol is TA,the rating is 0 to 70,the unit is ;(4):the parameter is storage temperature range,the symbol is Tstg,the rating is -65 to 150,the unit is
