DescriptionThe SN74HC251NSRE4 contain full binary decoding to select 1-of-8 data sources and feature strobe-controlled complementary 3-state outputs.The 3-state outputs can interface with and drive data lines of bus-organized systems.The outputs are disabled when OE is high.
Features of the SN74HC251NSRE4 are:(1)wide operating voltage range of 2V to 6V;(2)high-current 3-state outputs interface directly with system bus or can drive up to 15 LSTTL loads;(3)low power consumption 80-A Max ICC;(4)typical tpd=9ns;(5)±6-mA output drive at 5V;(6)low input current of 1A Max;(7)perform parallel to serial conversion;(8)complementary outputs provide true and inverted data.
The absolute maximum ratings of the SN74HC251NSRE4 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 ±35,the unit is mA;(5):the parameter is continuous current through,the symbol is VCC to GND,the rating is ±70,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
