† 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. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating

conditions.

‡ 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, where the less positive (more negative) limit is designated as minimum, is used in this data sheet for threshold voltages

only.

# Input voltage range is the voltage range that, if exceeded at either input, will cause the receiver to cease functioning properly.

NOTES:

3. This applies with the less-positive receiver input grounded.

4. This applies with the more-positive receiver input at 15 V or the more negative receiver input at −15 V.
