Notes:
1. C_L includes probe and jig capacitance.
2. Waveform 1 is for an output with internal conditions such that the output is LOW except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is HIGH except when disabled by the output control.
3. All input pulses are supplied by generators having the following characteristics: PRR<10MHz, Z_O = 50Ω, t_r ≤2.5ns, t_f ≤2.5ns.
4. The outputs are measured one at a time with one transition per measurement.
5. t_PLZ and t_PHZ are the same as t_dis.
6. t_PZL and t_PZH are the same as t_en.
7. t_PLH and t_PHL are the same as t_pd.

Applications
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a 3.0V supply, the control or
select pins may be driven low to 0V and high to 3.6V. Driving the control or select pins Rail-toRail minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/
output or control pins.
