74AHC1G66; 74AHCT1G66
Single-pole single-throw analog switch
6.2 Pin description
7. Functional description
[1] H = HIGH voltage level; L = LOW voltage level.
8. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output voltage ratings are observed.
[2] For TSSOP5 and SC-74A packages: above 87.5 °C the value of P
tot
derates linearly with 4.0 mW/K.
