Caution: 1.Permanent damage to the chip may result if absolute maximum ratings are exceeded.
2. Never apply more than 7.0 V to any of the pins of the 5- or 4-V version or 4.3 V to any
of the pins of the 3-V version.
Notes: 1. Voltage applied to the VCC1 pin.
Never exceed the maximum rating of V
CL
in the low-power version (3-V version)
because both the VCC1 and V
CL
pins are connected to the V
CC
power supply.
2. It is an operating power supply voltage pin on the chip.
Never apply power supply voltage to the V
CL
pin in the 5- or 4-V version.
Always connect an external capacitor between the V
CL
pin an ground for internal voltage
stabilization.
