MC10H643_16 Datasheet, PDF (1/6 Pages) ON Semiconductor – Dual Supply ECL to TTL 1:8 Clock Driver

MC10H643
Dual Supply ECL to TTL
1:8 Clock Driver
Description
The MC10H643 is a dual supply, low skew translating
1:8 clock driver. Devices in the ON Semiconductor H643 translator
series utilize the PLCC−28 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 48 mA TTL output stage, with AC
performance specified into a 50 pF 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 MC10H643 is compatible with MECL 10H™ ECL logic levels.
