Typicals represent average readings at 25°C and V
Guaranteed by design and not subject to production test. Resistor-terminal capacitance tests are measured with 2.5 V bias on the measured terminal.
The remaining resistor terminals are left open circuit.
See the timing diagram in Figure 3 for location of measured values. All input control voltages are specified with t
timed from a voltage level of 1.6 V. Switching characteristics are measured using V
of 1 V/μs should be maintained.
Propagation delay depends on the value of V
