TIMING CHARACTERISTICS
(V+ = +2.7V to +5.5V, T
A
= -40°C to +85°C, unless otherwise noted. Typical values are at T
A
= +25°C.) (Note 1)
SYMBOL
PARAMETER
Note 1:
Specifications from 0°C to -40°C are guaranteed by design, not production tested.
Note 2:
For supply current, SMBus logic inputs driven to 0 or V+.
Note 3:
Data hold and set-up times measured from falling edge of 9th clock.
Note 4:
Must be driven to GND, V+, or floating. See
SMBus Addressing
section.
Note 5:
The SMBus logic block is a static design and will work with clock frequencies down to DC. While slow operation is possible,
it violates the 10kHz minimum clock frequency and SMBus specifications and may use excessive space on the bus.
