SY100HA643
DESCRIPTION
The SY100HA643 is an enhanced dual supply, low skew
translating 1:8 clock driver. Devices in the Micrel-Synergy
H600 translators series utilize the 28-lead PLCC for optimal
power pinning, signal flow through and electrical
performance. The dual-supply HA643 is similar to the H641,
which is a single-supply 1:9 version of the same function,
with higher performance than the H643 versions.
The device features a 48mA TTL output stage, with AC
performance specified into a 20pF 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 pulldowns)
the latch is transparent. A HIGH on the enable pin (EN)
forces all outputs LOW.
The 100HA643 is compatible with 100K ECL logic levels.
