description
This 20-bit buffer is designed for 3-V to 3.6-V V_CC
operation and SSTL_3 input levels.
Data flow from A to Y is controlled by the
output-enable (OE). When OE is high, the outputs
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.
The SN74SSTL16847 is characterized for
operation from 0°C to 70°C.
