LT1719
ELECTRICAL CHARACTERISTICS
Note 8: Because of internal hysteresis, there is no small-signal region
in which to measure gain. Proper operation of internal circuity is
ensured by measuring VOH and VOL with only 10mV of overdrive.
Note 9: Propagation delay measurements made with 100mV steps.
Overdrive is measured relative to VTRIP±.
Note 10: tPD cannot be measured in automatic handling equipment
with low values of overdrive. The LT1719 is 100% tested with a
100mV step and 20mV overdrive. Correlation tests have shown that
tPD limits can be guaranteed with this test, if additional DC tests are
performed to guarantee that all internal bias conditions are correct.
Note 11: Propagation Delay Skew is defined as:
tSKEW = |tPDLH – tPDHL|
