POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
description (continued)
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16831 is characterized for operation from –40°C to 85°C.
