Signal description
During all operations, V

All of the input and output signals must be held high or low (according to voltages of V
V
described next.
Serial Data Output (Q)
This output signal is used to transfer data serially out of the device. Data is shifted out on the
falling edge of Serial Clock (C).
Serial Data Input (D)
This input signal is used to transfer data serially into the device. It receives instructions,
addresses, and the data to be written. Values are latched on the rising edge of Serial Clock
(C).
Serial Clock (C)
This input signal provides the timing of the serial interface. Instructions, addresses, or data
present at Serial Data Input (D) are latched on the rising edge of Serial Clock (C). Data on
Serial Data Output (Q) change from the falling edge of Serial Clock (C).
Chip Select (S)
When this input signal is high, the device is deselected and Serial Data Output (Q) is at high
impedance. The device is in the Standby Power mode, unless an internal Write cycle is in
progress. Driving Chip Select (S) low selects the device, placing it in the Active Power mode.
After power-up, a falling edge on Chip Select (S) is required prior to the start of any
instruction.
Hold (HOLD)
The Hold (HOLD) signal is used to pause any serial communications with the device without
deselecting the device.
During the Hold condition, the Serial Data Output (Q) is high impedance, and Serial Data
Input (D) and Serial Clock (C) are Don’t Care.
To start the Hold condition, the device must be selected, with Chip Select (S) driven low.
