Product data sheet Rev. 02 — 2 September 2008 5 of 20 NXP Semiconductors 74HC4851; 74HCT4851 8-channel analog MUX/DEMUX with injection-current effect control 7. Functional description [1] H = HIGH voltage level; L = LOW voltage level; X = don’t care. 8. Limiting values [1] The minimum and maximum input voltage rating may be exceeded if the input clamping current rating is observed. [2] The minimum and maximum switch voltage rating may be exceeded if the switch clamping current rating is observed. [3] For SO16 package: Ptot derates linearly with 8 mW/K above 70 °C. For TSSOP16 package: Ptot derates linearly with 5.5 mW/K above 60 °C. For DHVQFN16 packages: Ptot derates linearly with 4.5 mW/K above 60 °C. Table 3.
