T7933

The T7933 is a column (segment) driver for small or medium-scale dot matrix graphic LCD.The T7933 realizes a low power LCD system using the CMOS Si-gate process.The T7933 generates timing signals for the display using a built-in oscillator and also controls the T7932 column (segment) LCD driver.

Features of the T7933 are:(1)row signal output for LCD;(2)LCD drive outputs is 32( low impedance );(3)built-in oscillator (additional external resistor and capacitor);(4)built-in voltage dividers for 1/16 and 1/32 duty cycle;(5)duty is 1/8,1/12,1/16,1/24,1/35;(7)low power consumption;(8)logic power supply is 5V±10%;(9)60-pin flat plastic package .

The absolute maximum ratings of the T7933 can be summarized as:(1):the item is supply voltage 1,the symbol is VDD,the rating is -0.3 to 7.0,the unit is V;(2):the item is supply voltage 2,the symbol is VLC1,LC4,LC5,the rating is VDD-13.5 to VDD+0.3,the unit is V;(3):the item is input voltage,the symbol is VIN,the rating is -0.3 to VDD+0.3,the unit is V;(4):the item is operating temperature,the symbol is Topr,the rating is -20 to 75,the unit is ;(5):the item is storage temperature,the symbol is Tstg,the rating is -55 to 125,the unit is .
