X24042

PIN CONFIGURATION

PIN DESCRIPTIONS

Serial Clock (SCL)

The SCL input is used to clock all data into and out of the

device.

Serial Data (SDA)

SDA is a bidirectional pin used to transfer data into and

out of the device. It is an open drain output and may be

wire-ORed with any number of open drain or open

collector outputs.

An open drain output requires the use of a pull-up

resistor. For selecting typical values, refer to the Pull-Up

Resistor selection graph at the end of this data sheet.

Address (A0)

A0 is unused by the X24042, however, it must be tied to

VSS to insure proper device operation.

Address (A1, A2)

The Address inputs are used to set the appropriate bits

of the seven bit slave address. These inputs can be used

static or actively driven. If used statically they must be

tied to VSS or VCC as appropriate. If driven they must be

driven to VSS or to VCC.
