SEMICONDUCTOR TECHNICAL DATA

Dual Supply
ECL-TTL 1:8 Clock Driver

The MC10H/100H643 is a dual supply, low skew translating 1:8 clock
driver. Devices in the Motorola H600 translator series utilize the 28–lead
PLCC for optimal power pinning, signal flow through and electrical
performance. The dual–supply H643 is similar to the H641, which is a
single–supply 1:9 version of the same function.

The device features a 48mA 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 pulldowns) the latch is transparent. A HIGH on the enable pin
(EN

) forces all outputs LOW.

The 10H version is compatible with MECL 10H ECL logic levels. The
100H version is compatible with 100K levels.
