Therefore, when connecting the power supply, observe the following sequence. Logic system power supply (VLS) or internal logic system power supply (VSS, VCC; VCC > VSS) / logic input / LCD drive power supply (VEE, VDD) It is possible to set voltage VEE to the same as VSS. When connecting the power supply when VEE = VSS, observe the following sequence and the recommended sequence figure shown below. Logic system power supply (VLS), internal logic system power supply (VSS, VCC; VCC > VSS) and low-level LCD drive power supply (VEE) / logic input / high-level LCD drive power supply (VDD) When disconnecting the power supply, follow the reverse sequence. Since the logic state of the internal circuit is unstable immediately after the logic system power is supplied, input CKV and SPV while initializing the internal circuit (minimum input clock number is 300 CKV). MODE1 and MODE2 should be set to "L" during the initializing period for setting the LCD drive output to VEE level. VDD VLS Input 0V VCC VSS, VEE Input pin setting Input pins other than CKV and SPV must be set to "H" or "L" level. Maximum ratings When connecting or disconnecting the power, this IC must be used within the range of the absolute maximum ratings. 9 LH1692 ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL VDD VLS Supply voltage VCC - VSS VEE - VSS VDD - VEE (VSS) Input voltage Storage temperature VIN TSTG APPLICABLE PINS VDD VLS VCC, VSS VEE, VSS VDD, VEE, VSS CKV, SPV, CE1, CE2, R/L, MODE1, MODE2, TEST1, TEST2 RATING -0.3 to +45.0 -0.3 to +7.0 -0.3 to +7.0 -0.3 to +45.0 -0.3 to +45.0 -0.3 to VLS + 0.3 -45 to +125 UNIT V V V V V V C 1, 2 NOTE NOTES : 1.
