FEATURES
DESCRIPTION
s Input frequencies up to 80MHz
s PECL-to-TTL version of popular ECLinPS E111
s Guaranteed low skew specification
s Latched input
s Differential ECL internal design
s VBB output for single-ended operation
s Single +5V supply
s Reset/enable
s Extra TTL and ECL power/ground pins
s Choice of ECL compatibility: MECL 10KH (10Hxxx)
or 100K (100Hxxx)
s ESD protection of 2000V
s Fully compatible with Motorola MC10H641/100H641
s Available in 28-pin PLCC package
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.
