Unless otherwise noted, Vstrobe = 2.4 V. All parameters with the exception of off-state open-collector output current are measured with the active
pullup connected to the sink output.
All typical values are at VCC = 5 V, TA = 25
°
C, and VIC = 0.
§Differential voltages are at the B input terminal with respect to the A input terminal.
The algebraic convention, in which the less positive (more negative) limit is designated as minimum, is used in this data sheet for threshold
voltages only.
#Only one output should be shorted to ground at a time, and duration of the short circuit should not exceed one second.
