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 noted, these limits are over the operating free-air temperature range.
4. Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
CC
or ground.
5. Typical values are at V
CC
= 3.3V, T
A
= +25°C ambient.
6. This parameter is guaranteed 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
tests, I
OS
tests should be performed last.
