Additional dynamic characteristics for 74HC2G66 and 74HCT2G66 …continued GND = 0 V; tr = tf = 6.0 ns; CL = 50 pF; unless otherwise specified. All typical values are measured at Tamb =25 °C. Symbol Parameter Conditions Min Typ Max Unit With fi = 1 MHz adjust the switch input voltage for a 0 dBm level at the switch output, (0 dBm = 1 mW into 50 Ω). Then Increase the input frequency until the dB meter reads −3dB. Fig 12. Test circuit for measuring total harmonic distortion Fig 13.
