COMMON-MODE TRANSIENT IMMUNITY

kV/μs

VCM ≥ ±1 kV, transient magnitude measured

between 20% and 80% of VCM, see Figure 37

and Figure 38

1 ADM2463E only.

2 The CMTI is the maximum common-mode voltage slew rate that can be sustained while maintaining specification compliant operation. VCM is the common-mode

potential difference between the logic and bus sides. The transient magnitude is the range over which the common mode is slewed. The common-mode voltage slew

rates apply to rising and falling common-mode voltage edges.

TIMING SPECIFICATIONS

VDD1 = 1.7 V to 5.5 V, VDD2 = 3.0 V to 5.5 V, TA = TMIN (−40°C) to TMAX (+125°C), unless otherwise noted. All typical specifications are at

TA = 25°C, VDD1 = VDD2 = 3.3 V, unless otherwise noted.
