Note 1: All specifications are 100% tested at TA = +25°C, unless otherwise noted. Specification limits over temperature (TA = TMIN
to TMAX) are guaranteed by design.
Note 2: Input Offset Voltage (VOS) is defined as the average of the two input offset voltages, measured by forcing first one output,
then the other to 1.4V. Input Offset Current (IOS) is defined the same way.
Note 3: Supply currents are measured with VQ driven to both VOH and VOL (not 1.4V).
Note 4: Propagation Delay (tPD) and Differential Propagation Delay (∆tPD) cannot be measured in automatic handling equipment
with low input overdrive values. Characterization and correlation tests have shown that tPD and ∆tPD limits can be guaran-
teed by design. Electrical Characteristic DC tests are performed to guarantee that all internal bias conditions are correct.
For low overdrive conditions, VOS is added to overdrive. Differential Propagation Delay is defined as ∆tPD = tPD+ - tPD-.
Note 5: Input latch setup time (tSU) is the interval in which the input signal must be stable prior to asserting the latch signal. The hold
time (tH) is the interval after the latch is asserted in which the input signal must be stable. These parameters are guaranteed
by design.
Note 6: Latch Propagation Delay (tLPD) is the delay time for the output to respond when the latch-enable pin is deasserted (see
Timing Diagram).
