8-DIGIT CALCULATOR WITH MARKER  
The IZ1236МR is a single chip CMOS LSI with 8-digitt arithmetic operation, with marker,  
LCD control, and auto power off function, designed for FEM LCD operation with a 1.5V  
power supply.  
FUNCTIONS:  
- basic arithmetical operations over eight-digit numbers;  
- operations with memory;  
- percentage calculation;  
- square root calculation;  
- calculation of reverse value of number;  
- operations with constants;  
- indication of additional operations.
