DESCRIPTION/ORDERING INFORMATION  
This 20-bit noninverting buffer/driver is designed for  
1.65-V to 3.6-V VCC 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.

The outputs, which are designed to sink up to 12 mA,  
include equivalent 26-Ω resistors to reduce overshoot  
and undershoot.  
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 holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors  
with the bus-hold circuitry is not recommended.
