Minimum SCL clock frequency is limited by the bus timeout feature, which resets the serial bus interface if either SDA or SCL is held low for
t TIMEOUT . Disable bus timeout feature for DC operation
t VD:ACK = SCL low to SDA (out) low acknowledge time
t VD:DAT = minimum SDA output data-valid time following SCL low transition
A master device must internally provide an SDA hold time of at least 300ns to ensure an SCL low state
The maximum SDA and SCL rise times are 300ns. The maximum SDA fall time is 250ns. This allows series protection resistors to be
connected between SDA and SCL inputs and the SDA/SCL bus lines without exceeding the maximum allowable rise time
The MSL2100 includes input filters on SDA, SCL, AD0, and AD1 inputs that suppress noise less than 50ns
Parameter is guaranteed by design, and is not production tested
Subject to thermal dissipation characteristics of the device
When mounted according to JEDEC JEP149 and JESD51-12 for a one-layer PCB, θ JA = 22°C/W and θ JC = 1.3°C/W
