DESCRIPTION

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.

The SN74ALVCH16827 is characterized for operation

from -40°C to 85°C.
