Product data sheet Rev. 03 — 15 February 2005 8 of 16 Philips Semiconductors 74ALVC14 Hex inverting Schmitt trigger 13. Transfer characteristics Test data is given in Table 9. Definitions test circuit: RT = Termination resistance should be equal to output impedance Zo of the pulse generator. CL = Load capacitance including jig and probe capacitance. RL = Load resistor. VEXT = Test voltage for switching times. Fig 7.
