2 / 11 page SN74CB3T16211 24BIT FET BUS SWITCH 2.5V/3.3V LOW VOLTAGE BUS SWITCH WITH 5V TOLERANT LEVEL SHIFTER SCDS147B − OCTOBER 2003 − REVISED JANUARY 2005 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 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, the output high-voltage (VOH) level is equal to approximately the VCC voltage level. Input Voltages Output Voltages 0 V ≈VCC − 1 V ≈VCC − 1 V VCC IN OUT CB3T Figure 1. Typical DC Voltage-Translation Characteristics The I/O port of this device has a pullup current source that maintains the output voltage at VCC when the device is ON and the input is greater than or equal to VCC − 1. Because of the pullup current source, the output voltage level may be less than VCC when the operating frequency is low and the I/O port is connected to a pulldown resistor. In order to maintain the output voltage at VCC, a pullup resistor must be connected to VCC, instead of a pulldown resistor to ground. The SN74CB3T16211 is organized as two 12-bit bus switches with separate output-enable (1OE, 2OE) inputs. It can be used as two 12-bit bus switches or as one 24-bit bus switch. When OE is low, the associated 12-bit bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is high, the associated 12-bit bus switch is OFF, and a high-impedance state exists between the A and B ports. 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.
