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.
