Cautions: 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 V or 4 V version or 4.3 V to
any of the pins of the 3 V version.
Notes: *1 Power supply voltage for V
CC1
pin
Never exceed the maximum rating of V
CL
in the low-power version (3 V version)
because both the V
CC1
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 V or 4 V version.
Always connect an external capacitor between the V
CL
pin and ground for internal
voltage stabilization.
