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 VCC 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 and ground for internal

voltage stabilization.
