DESCRIPTION/ORDERING INFORMATION (CONTINUED)
Figure 1. Typical DC Voltage Translation Characteristics
The SN74CB3T3245 is an 8-bit bus switch with a single ouput-enable (OE) input and a standard '245 pinout.
When OE is low, the 8-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 8-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.
