28-pin SSOP package (H)
Description
Pericom Semiconductor聮s PI6C clock series is produced using the
company聮s advanced submicron CMOS technology, achieving
industry leading speed.
The PI6C182B, a high-speed low-noise 1-10 noninverting buffer
designed for SDRAM clock buffer applications, supports higher
frequencies up to 140 MHz.
At power up all SDRAM output are enabled and active. The I
2
C
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 all
outputs.
Note:
Purchase of I

C components from Pericom conveys a license to
use them in an I
2
C system as defined by Philips.
