Part Number	MC100H643 Datasheet
Manufacturer	onsemi
Overview	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 an. 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.
