Note 1: 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 2: Propagation Delay (tPD) and Differential Propagation Delay (∆tPD) cannot be measured in automatic handling equipment

with low input overdrive values. The MAX912/MAX913 are sample tested to 0.1% AQL with a 1V step and 500mV overdrive

at +25°C only. Correlation tests show that tPD and ∆tPD can be guaranteed with this test, if additional DC tests are per-

formed to guarantee that all internal bias conditions are correct. For low overdrive conditions, VOS is added to the over-

drive. Differential Propagation Delay is defined as:

∆tPD = tPD+ – tPD-.

Note 3: 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 4: Latch Propagation Delay (tLPD) is the delay time for the output to respond when the latch-enable pin is deasserted.
