• Description: Dual Digitally Programmable Potentiometers Dpp? With 64 Taps And I?c Interface
• Manufacturer: Catalyst Semiconductor

WRITE CYCLE LIMITS
Over recommended operating conditions unless otherwise stated.
The write cycle is the time from a valid stop condition of a write sequence to the end of the internal program/erase
cycle. During the write cycle, the bus interface circuits are disabled, SDA is allowed to remain high, and the
device does not respond to its slave address.
RELIABILITY CHARACTERISTICS
Over recommended operating conditions unless otherwise stated.
Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
