1 Typicals represent average readings at 25°C and VDD = 5 V.
2 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.
3 See the timing diagram in Figure 3 for location of measured values. All input control voltages are specified with tR = tF = 1 ns (10% to 90% of VDD) and
timed from a voltage level of 1.6 V. Switching characteristics are measured using VDD = 3 V or 5 V. To avoid false clocking, a minimum input logic slew rate
of 1 V/μs should be maintained.
4 Propagation delay depends on the value of VDD, RL, and CL (see the Applications section).
