MC10H641_06 Datasheet, PDF (1/10 Pages) ON Semiconductor – Single Supply PECL to TTL 1:9 Clock Distribution Chip

MC10H641, MC100H641
Single Supply PECL to TTL
1:9 Clock Distribution Chip
Description
The MC10H/100H641 is a single supply, low skew translating 1:9
clock driver. Devices in the ON Semiconductor H641 translator series
utilize the PLCC−28 for optimal power pinning, signal flow through
and electrical performance.
The device features a 24 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 pulldown) the latch is transparent. A
HIGH on the enable pin (EN) forces all outputs LOW. Both the LEN
and EN pins are positive ECL inputs.
The V_BB output is provided in case the user wants to drive the
device with a single−ended input. For single−ended use, the V_BB
should be connected to the D input and bypassed with a 0.01 mF
capacitor.
The 10H version of the H641 is compatible with positive
MECL 10H™ logic levels. The 100H version is compatible with
positive 100K levels.
