For the 3-V operation, VCC1 or VCC2 is specified from 3 V to 3.6 V. SWITCHING CHARACTERISTICS: VCC1 at 5 V, VCC2 at 3.3 V OPERATION over recommended operating conditions (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tpLH, tpHL Propagation delay 24 36 49 ns PWD Pulse-width distortion |tpHL – tpLH| (1) 1 2 ns tsk(pp) Part-to-part skew (2) 10 ns tsk(o) Channel-to-channel output skew (3) 0.2 10 ns tr Output signal rise time See Figure 1 2 ns tf Output signal fall time See Figure 1 2 ns tfs Failsafe output delay time from input power loss See Figure 2 3 μs (1) Also referred to as pulse skew. (2) tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices operate with the same supply voltages, at the same temperature, and have identical packages and test circuits. (3) tsk(o) is the skew between specified outputs of a single device with all driving inputs connected together and the outputs switching in the same direction while driving identical specified loads.
