NOTES:
3. The differential-input threshold voltage (VT )
is defined as the d-c differential-input voltage
(VID) required to force the output of the sense
amplifier to the logic gate threshold voltage
level.
4. Common-mode input firing voltage is the
minimum common-mode voltage that will exceed
the dynamic range of the 'input at the
specified conditions and cause the logic output
to switch. The specifed common-mode input
signal is applied with a strobe-enable present.
5. Differential-input overload recovery time
is the time necessary for the device to recover
from the specified common-mode-input overlo~d
signal prior to the strobe-enable signal.
6. Common"mode~inputoverloadrecovery time
is the time necessary for the device to recover
from the speCified common-mode-input overload
signal prior to the strobe-enable signal.
