2 / 16 page www.ti.com DESCRIPTION/ORDERING INFORMATION (CONTINUED) VCC ≈VCC 5.5 V 0 V NOTE A: If the input high voltage (VIH) level is greater than or equal to VCC – 1 V, and less than or equal to 5.5 V, then the output high voltage (VOH) level will be equal to approximately the VCC voltage level. Input Voltages Output Voltages 0 V ≈VCC − 1 V ≈VCC − 1 V VCC IN OUT CB3T OE B A SW 2 1 4 SN74CB3T1G125 SINGLE FET BUS SWITCH 2.5-V/3.3-V LOW-VOLTAGE SWITCH WITH 5-V-TOLERANT LEVEL SHIFTER SCDS150A – OCTOBER 2003 – REVISED SEPTEMBER 2006 Figure 1. Typical DC Voltage Translation Characteristics This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
