X24C04
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 X24C04, however, it must be tied to V_SS
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
V_SS or V_CC as appropriate. If driven they must be
driven to V_SS or to V_CC.
