(2) tsk(pp) is the magnitude of the difference in propagation delay times between any specified pins 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. 14 Submit Documentation Feedback Copyright © 2006–2015, Texas Instruments Incorporated Product Folder Links: ISO7220A ISO7220B ISO7220C ISO7220M ISO7221A ISO7221B ISO7221C ISO7221M |
