16COM/60SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
S6A2068
NOTES:
*1) The supply current value from VDD when condition is as follows
VDD = 5V, VSS = 0V, V5 = -2V
VDD = 3V, VSS = 0V, V5 = -2V
*2) Applied to the voltage drop occurring from terminals VDD, V1, V4 and V5 to each common terminal (C1-C16) when
0.1mA is flown in or out to and from all COM and SEG terminals, and also to voltage drop occurring from terminals
VDD, V2, V3 and V5 to each SEG terminal (S1-S60). When the output level is at VDD, V1 or V2 level, 0.1mA is flown out,
while 0.1mA flow in when the output level is at V3, V4 or V5 level. This occurs when 5 V or -5 V is input to VDD, V1 and
V3 or to V2, V4, and V5 respectively.
*3) and *4): Refer to oscillator circuit and input the voltage listed in the table bellow to V1-V5
