Note
• Common mode transient immunity in a logic high level is the maximum tolerable (positive) dVCM/dt on the leading edge of the common mode
pulse (VCM) to assure that the output will remain in a logic high state (i.e., VO > 2 V). Common mode transient immunity in a logic low level
the maximum tolerable (negative) dVCM/dt on the trailing edge of the common mode pulse signal (VCM to assure that the output will remain
in logic low state, i.e., VO > 0.8 V).
The 1.9 kΩ load represents 1 TTL unit load of 1.6 mA and the 5.6 kΩ pull-up resistor.
The 4.1 kΩ load represents 1 LSTTL unit load of 0.36 mA and the 6.1 kΩ pull-up resistor.
