Description

The M74HC393B1R is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C2MOS technology.This enables count truncation and allows the implementation of divide by N counter configurations.All inputs are equipped with protection circuits against static discharge and transient excess voltage.
 
Features of the M74HC393B1R are:(1)high speed:fMAX = 79 MHz (TYP.) at VCC = 6V;(2) low power dissipation:icc = 4a(max.) at ta=25;(3)high noise immunity:VNIH=VNIL=28%VCC(min.);(4)symmetrical output impedance:|IOH|=IOL=4mA (MIN);(5)balanced propagation delays:tPLH =-tPHL;(6)wide operating voltage range:VCC(OPR)=2V to 6V;(7)pin and function compatible with 74 series 393.

The absolute maximum ratings of the M74HC393B1R can be summarized as:(1):the symbol is VCC,the parameter supply voltage,the value -0.5 to +7,the unit is V;(2):the symbol is VI,the parameter DC input voltage,the value -0.5 to VCC + 0.5,the unit is V;(3):the symbol is VO,the parameter DC output voltage,the value -0.5 to VCC + 0.5,the unit is V;(4):the symbol is IIK,the parameter DC input diode current,the value ±20,the unit is mA;(5):the symbol is IOK,the parameter DC output diode current,the value ±20,the unit is mA;(6):the symbol is IO,the parameter DC output current,the value ±25,the unit is mA;(7):the symbol is ICC or IGND,the parameter DC VCC or ground current,the value ±50,the unit is mA;(8):the symbol is PD,the parameter power dissipation,the value 500,the unit is mW;(9):the symbol is Tstg,the parameter storage temperature,the value -65 to +150,the unit is ;(10):the symbol is TL,the parameter lead temperature(10 sec),the value 300,the unit is .
