PIn DESCRIPTIOnS
SCL
This input clock pin is used to synchronize the data transfer
to and from the device.
SDA
The SDA is a Bi-directional pin used to transfer addresses
and data into and out of the device. The SDA pin is an open
drain output and can be wire-Or'ed with other open drain or
open collector outputs. The SDA bus requires a pullup resistor
to Vcc.
A0, A1, A2
The A0, A1 and A2 are the device address inputs. The IS24C02A
uses the A0, A1, and A2 for hardware addressing and a total
of 8 devices may be used on a single bus system. When
the A0, A1, or A2 inputs are left floating, the input internally
defaults to zero.

PIN CONFIGURATION
8-pad Dfn
The IS24C04A uses A1 and A2 pins for hardwire addressing
and a total of four devices may be addressed on a single bus
system. The A0 pin is a no connect in the IS24C04A. When
the A1 or A2 input is left floating, the input internally defaults
to zero.
The IS24C08A only uses the A2 input for hardwire addressing
and a total of two devices may be addressed on a single
bus system. The A0 and A1 pins are no connects in the
IS24C08A. When the A2 input is left floating, the input internally
defaults to zero.
These pins are not used by IS24C16A . The A0, A1, and A2
pins are no connects in the IS24C16A.
WP
WP is the Write Protect pin. If the WP pin is tied to V
the IS24C02A, IS24C04A, IS24C08A and IS24C016A,
the entire array becomes Write Protected (Read only).
When WP is tied to GND or left floating normal read/write
operations are allowed to the device.
