Notes:

1.

A-to-B data flow shown; B-to-A flow control is the same, except using CEBA, LEBA, and OEBA.

2.

Data prior to LEAB LOW-to-HIGH Transition

H = HIGH Voltage Level. L = LOW Voltage Level.

X = Don’t Care. Z = High Impedance.

3.

Operation beyond the limits set forth may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature

range.

This parameter is specified but not tested.

7.

Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample

and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting

of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
