This 20-bit noninverTIng buffer/driver is designed for 1.65-V to 3.6-V VCC operaTIon.
The SN74ALVCH16827 is composed of two 10-bit secTIons with separate output-enable signals. For either 10-bit buffer secTIon, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the high-impedance state.
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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
