Description
The PI6C182B is a high-speed low-noise 1-10 non-inverting buffer
designed for SDRAM clock buffer applications and supports higher
frequencies up to 140 MHz.
At power up all SDRAM output are enabled and active. The I
Serial control may be used to individually activate/deactivate any
of the 10 output drivers.
The output enable (OE) pin may be pulled low to Hi-Z state on
all outputs.
