DESCRIPTION/ORDERING INFORMATION
This 20-bit noninverting buffer/driver is designed for
1.65-V to 3.6-V V
CC
operation.
The SN74ALVCH162827 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.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
SN74ALVCH162827
20-BIT BUFFER/DRIVER
WITH 3-STATE OUTPUTS
SCES013H–JULY 1995–REVISED AUGUST 2004
The outputs, which are designed to sink up to 12 mA,
include equivalent 26-
resistors to reduce overshoot
and undershoot.
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.
