Product data sheet Rev. 2 — 26 November 2010 6 of 19 NXP Semiconductors 74CBTLV3257 Quad 1-of-2 multiplexer/demultiplexer 9.2 ON resistance [1] Typical values are measured at Tamb =25 C and nominal VCC. [2] Measured by the voltage drop between the A and B terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two (A or B) terminals. 9.3 ON resistance test circuit and graphs Table 7. Resistance RON At recommended operating conditions; voltages are referenced to GND (ground = 0 V); for test circuit see Figure 7.
