DUAL SUPPLY

OCTAL ECL-TO-TTL

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.
