MC10H641

Single Supply PECL to TTL 1:9 Clock Distribution Chip

ON Semiconductor 

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 VBB output is provided in case the user wants to drive the

device with a single−ended input. For single−ended use, the VBB

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.
