3 / 37 page SN74AVCH4T245 www.ti.com SCES577E – JUNE 2004 – REVISED NOVEMBER 2015 5 Description (continued) The VCC isolation feature ensures that if either VCC input is at GND, then both ports are in the high-impedance state. The bus-hold circuitry on the powered-up side always stays active. Active bus-hold circuitry holds unused or undriven data inputs at a valid logic state. Use of pull-up or pull-down resistors with the bus-hold circuitry is not recommended. The bus-hold circuitry on the powered-up side always stays active. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
