Product data sheet Rev. 06 — 18 January 2008 10 of 17 NXP Semiconductors 74LVC4245A Octal dual supply translating transceiver; 3-state [1] VCCI is the supply voltage associated with the data input port. [2] VCCO is the supply voltage associated with the output port. Test data is given in Table 8. Definitions for test circuit: RL = Load resistance. CL = Load capacitance including jig and probe capacitance. RT = Termination resistance should be equal to output impedance Zo of the pulse generator. Fig 8.
