Product data sheet Rev. 8 — 21 November 2011 6 of 14 NXP Semiconductors HEF4014B 8-bit static shift register 11. Dynamic characteristics [1] The typical values of the propagation delay and transition times are calculated from the extrapolation formulas shown (CL in pF). [2] tt is the same as tTHL and tTLH.
