SC3414
1.5V 10/12 DIGIT CALCULATOR CIRCUIT
DESCRIPTION
The SC3414 is a single-chip LSI CMOS calculator with 12-digits 2-
memory or 10-digits 2-memory. SC3414 can drive the liquid crystal
display (LCD) with single power supply. Single power supply
operation, wide operating voltage and lower power consumption make
it suitable for 1.5V solar battery operated calculator. Beside SC3414
can be selected as Auto Power OFF or Manual Power OFF with Lock
Key. It also can be selected as Memory Hold or Clear at Power OFF.
