VIH(max) = VCC + 2.0V for pulse width less than 6ns.
VIL(min) = VSS - 2.0V for pulse width less than 6ns.
Revised the address pin sequence of TSOP-II pin configuration on page 2
to be compatible with industrial convention. (No function specifications and
applications changed and all characteristics kept same as Rev 1.3 )
Deleted Commercial Grade
Added PKG type : 36-ball 6mm x 8mm TFBGA
Deleted WRITE CYCLE Notes :
1.WE#,CE# must be high during all address transitions. In page 6.

2.Device is continuously selected OE# = low, CE# = low.
3.Address must be valid prior to or coincident with CE# = low,; otherwise tAA is the limiting parameter.
4.tCLZ, tOLZ, tCHZ and tOHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
5.At any given temperature and voltage condition, tCHZ is less than tCLZ , tOHZ is less than tOLZ.

Notes :
1.A write occurs during the overlap of a low CE#, low WE#.
2.During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be
placed on the bus.
3.During this period, I/O pins are in the output state, and input signals must not be applied.
4.If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state.
5.tOW and tWHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
