MC100H643FN

Dual Supply ECL to TTL 1:8 Clock Driver

ON Semiconductor 

MC10H643, MC100H643

Dual Supply ECL to TTL

1:8 Clock Driver

Description

The MC10H/100H643 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 10H version is compatible with MECL 10H™ ECL logic levels.

The 100H version is compatible with 100K levels.
