translating 1:8 clock driver. Devices in the Micrel 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.
performance specified into a 20pF load capacitance.
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.
