AD16315

The AD16315 is a VFD(vacuum fluorecent display or fluorescent indicator panel)driver that is driven on a 1/4 to 1/2 duty factor.It consists of 16 segments and 4 grids output lines,8 segments/grid output driving lines,a display memory,a control circuit,and a key scan circuit.Serial data is input to the AD16315 through a 3-wire serial interface for a single-chip microcomputer.

The absolute maximum ratings of the AD16315 can be summarized as:(1):the parameter is logic supply voltage,the symbol is VDD,the rating is -0.5 to +6.0,the unit is V;(2):the parameter is driver supply voltage,the symbol is VEE,the rating is VDD+0.5 to VDD-40,the unit is V;(3):the parameter is logic input voltage,the symbol is VI1,the rating is -0.5 to VDD+0.5,the unit is V;(4):the parameter is VFD driver output voltage,the symbol is Vo2,the rating is VEE-0.5 to VDD+0.5,the unit is V;(5):the parameter is LED driver output current,the symbol is Io1,the rating is ±20,the unit is mA;(6):the parameter is VFD driver output current,the symbol is Io2,the rating is -40(grid),-15(segment),the unit is mA;(7):the parameter is power dissipation,the symbol is PD,the rating is 800,the unit is mW;(8):the parameter is operating ambient temperature,the symbol is TA,the rating is -25 to +85,the unit is ;(9):the parameter is storage temperature,the symbol is Tstg,the rating is -50 to +150,the unit is .
