DESCRIPTION
This 20-bit noninverting buffer/driver is designed for
1.65-V to 3.6-V V_CC 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 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 SN74ALVCH16827 is characterized for operation
from -40°C to 85°C.
