H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = HIGH Impedance.
A-to-B data flow is shown, B-to-A data flow is similar but uses OEBA, LEBA, andCLKBA.
Output level before the indicated steady-state input conditions were established.
Output level before the indicated steady-state input conditions were established, provided that CLKAB was LOW before LEAB went LOW.
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.
Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
CC
or ground.
Typical values are at V
= 5.0V, T
= +25C ambient.
This parameter is specified but not tested.
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
tests should be performed last.
10. Tested at +25C.
