MC10H641/D

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.

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.
