SN74ALVCH162827
20-BIT BUFFER/DRIVER
WITH 3-STATE OUTPUTS Memberof Texas Instruments Widebus™
Family Output Ports Equivalent 26-Ω Series
Resistors, No External Resistors Are
RequiredThis 20-bit noninverting buffer/driveris designed for
1.65-Vto 3.6-V operation.
The SN74ALVCH162827is composedof two 10-bit
sections with output-enable signals. For
either 10-bit buffer section, the two output-enable
(1OE1 and 1OE2or 2OE1 and 2OE2) inputs must
both be low for correspondingY outputsto be
active.If either input is high, the
outputs of that buffer section are in the
high-impedance
The outputs, which are designedto sink upto12 mA,
include equivalent resistorsto reduce overshoot
and undershoot. ensure the state during power up power down, should be tiedto VCC througha
pullup resistor; minimum valueof the resistoris
determined by current-sinking capability of the
driver.
with the bus-holdis not recommended.
