Product data sheet Rev. 08 — 2 April 2010 8 of 19 NXP Semiconductors HEF4094B 8-stage shift-and-store register [1] The typical values of the propagation delay and transition times are calculated from the extrapolation formulas shown (CL in pF). tPLZ LOW to OFF-state propagation delay OE to QPn; see Figure 8 5 V - 80 160 ns 10 V - 40 80 ns 15 V - 30 60 ns tsu set-up time D to CP; see Figure 9 5 V 60 30 - ns 10 V 20 10 - ns 15 V 15 5 - ns th hold time D to CP; see Figure 9 5 V +5 −15 - ns 10 V 20 5 - ns 15 V 20 5 - ns tW pulse width minimum LOW clock pulse; see Figure 6 5 V 60 30 - ns 10 V 30 15 - ns 15 V 24 12 - ns minimum HIGH strobe pulse; see Figure 7 5 V 40 20 - ns 10 V 30 15 - ns 15 V 24 12 - ns fmax maximum frequency see Figure 6 5 V 5 10 - MHz 10 V 11 22 - MHz 15 V 14 28 - MHz Table 7. Dynamic characteristics …continued VSS = 0 V; Tamb = 25 °C; for test circuit see Figure 10; unless otherwise specified. Symbol Parameter Conditions VDD Extrapolation formula Min Typ Max Unit Table 8. Dynamic power dissipation VSS = 0 V; tr = tf ≤ 20 ns; Tamb = 25 °C. Symbol Parameter VDD Typical formula for PD (μW) where: PD dynamic power dissipation 5 V PD = 2100 × fi + Σ(fo × CL) × VDD2 fi = input frequency in MHz, fo = output frequency in MHz, CL = output load capacitance in pF, VDD = supply voltage in V, Σ(f o × CL) = sum of the outputs. 10 V PD = 9700 × fi + Σ(fo × CL) × VDD2 15 V PD = 26000 × fi + Σ(fo × CL) × VDD2 |
