Reading data
Set the AS/DS pin (pin 43) at low level to specify address input. Specify the address in the lowest seven bits. Set the
top bit to 1.
Set the AS/DS pin (pin 43) at high level to specify data input. Set the STB pin (pin 44) at high level to cause the LSI
to output the data.

1 = 4.0 V
Note: AD0 to AD7 use N-channel open-drain outputs. The standard values for tp
LH
1 and tp
HL
1 are for an output load capacitance of 50 pF, an external
pull-up resistor of 2.7 k
, and an output level of 5.0 V.
