SN74CB3T16212 24-BIT FET BUS-EXCHANGE SWITCH, 2.5-V/3.3-V LOW-VOLTAGE BUS SWITCH WITH 5-V-TOLERANT LEVEL SHIFTER SCDS157A – OCTOBER 2003 – REVISED FEBRUARY 2005 Figure 1. Typical DC Voltage Translation Characteristics The SN74CB3T16212 operates as a 24-bit bus switch or as a 12-bit bus exchange that provides data exchanging between four signal ports. The select (S0, S1, S2) inputs control the data path of the bus-exchange switch. When the bus-exchange switch is ON, the A port is connected to the B port, allowing bidirectional data flow between ports. When the bus-exchange switch is OFF, a high-impedance state exists between the A and B ports. This device is fully specified for partial-power-down applications using I off. 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, each select input should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
