Figure 2-I shows a basic test circuit for measuring on-resistance, r DS(ON) ,for the MAX326/27. Figure 2-J shows how r DS(ON) changes with various analog inputs and supply combinations. Although specified at TTL threshold levels, the logic thresh-old is about 1.5 V± 0.2 V. The IC switches properly with CMOS input levels from -15 V to +15V. Never allow logic levels to exceed supply voltages in any circuit!
