Octal latched transceiver with dual enable; 3-state
[1]
For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
[2]
This parameter is valid for any VCC between 0 V and 2.1 V, with a transition time of up to 10 ms. From VCC = 2.1 V to VCC = 5 V 10 %,
a transition time of up to 100
s is permitted.
[3]
Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[4]
This is the increase in supply current for each input at 3.4 V.
