SN74LVCH16T245
16-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES635A – JULY 2005 – REVISED AUGUST 2005
Active bus-hold circuitry holds unused or undriven data inputs at a valid logic state. Use of pullup or pulldown
resistors with the bus-hold circuitry is not recommended.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The VCC isolation feature ensures that if either VCC input is at GND, then all outputs are in the high-impedance
state. 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 pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
