_______________________________________________________________________________________
Note 1: All parameters are tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 2: Guaranteed by design; not production tested.
Note 3: A master device must provide a hold time of at least 300ns for the SDA signal (referred to VIL of the SCL signal) to bridge
the undefined region of SCL’s falling edge.
Note 4: Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 x VCC and 0.7 x VCC.
Note 5: ISINK
≤ 6mA. Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 x VCC and 0.7 x VCC.
Note 6: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
Note 7: The MAX6621 must drive a more restrictive time to allow for quantized sampling errors by a client yet still attain the mini-
mum time less than 500μs. tBIT limits apply equally to tBIT-A and tBIT-M.
Note 8: The minimum and maximum bit times are relative to tBIT defined in the timing negotiation pulse.
Note 9: Extended trace lengths can appear as additional nodes.
Note 10: The client may deassert its low idle drive prior to the falling edge of the first bit of the message by using the rising edge to
detect a message start. However, the time delay must be sufficient to qualify the rising edge as a true message rather than
a noise spike.
Note 11: The message stop is defined by two consecutive periods when the bus has no rising edge. Tolerance around this time is
based on the tBIT-M error budget.
Note 12: tSETUP is not additive with tSTOP. Rather, these times may overlap.
TIMING CHARACTERISTICS (continued)
(
Typical Application Circuit, VCC = +3V to +3.6V, VREF = +0.95V to +1.26V, TA = -20°C to +120°C, unless otherwise noted. Typical
values are at VCC = +3.3V, VREF = +1.0V, TA = +25°C.) (Note 2)
