PROGRAMMABLE CALCULATOR WITH 10-BIT DUAL DISPLAY

DESCRIPTION

The SC3449 is a monolithic CMOS circuit for scientific calculators,

having the basic calculation, the memory calculation, fraction calculation,

percentage calculation, scientific function calculation, statistics back to

return to compute, degree, cent, second calculation etc. ,and you can

directly press the key according to the sequence of the formulas, while

the calculators will automatically operate in terms of the algorithm. Using

a 3V power supply it can display ten arithmetic figures, 12 characters

composing of lattice, and the state mark of the calculation. The

calculator can turn off by itself.
