For the 3-V operation, VCC1 or VCC2 is specified from 3 V to 3.6 V. SWITCHING CHARACTERISTICS VCC1 = VCC2 = 3.3 V, over recommended operating conditions (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tpLH, tpHL Propagation delay 290 400 485 ns ISO722xA See Figure 1 PWD Pulse-width distortion |tpHL – tpLH| (1) 1 18 ns tpLH, tpHL Propagation delay 25 40 52 ns ISO722xC See Figure 1 PWD Pulse-width distortion |tpHL – tpLH| (1) 1 3 ns ISO722xA 190 tsk(pp) Part-to-part skew(2) ns ISO722xC 10 ISO722xA 3 15 tsk(o) Channel-to-channel output skew (3) ns ISO722xC 0.2 1 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.
