SY10H641A

SY100H641A

The SY10/100H641A are single supply, low skew

translating 1:9 clock drivers. Devices in the Synergy H600

translator series utilize the 28-lead PLCC for optimal

power pinning, signal flow-through and electrical

performance.

The devices feature a 24mA TTL output stage with

AC performance specified into a 50pF load capacitance.

A latch is provided on-chip. When LEN is LOW (or left

open, in which case it is pulled LOW by the internal pull-

downs), the latch is transparent. A HIGH on the enable

pin (EN) forces all outputs LOW.

The 10H version is compatible with MECL 10KH ECL

logic levels. The 100H version is compatible with 100K

levels.
