MC10H643 Dual Supply ECL to TTL 1:8 Clock Driver Description The MC10H643 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 and electrical performance. The dual-supply H643 is similar to the H641, which is a single-supply 1:9 version of the same function. The device features 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 MC10H643 is compatible with MECL 10H™ ECL logic levels. www.onsemi.com PLCC−28 FN SUFFIX CASE 776−02 Features • • • • • • • • • • ECL/TTL Version of Popular ECLinPS™ E111 Low Skew Within Device 0.5 ns Guaranteed Skew Spec Part-to-Part 1.0 ns Latch Differential Internal Design VBB Output Dual Supply Reset/Enable Multiple TTL and ECL Power/Ground Pins These Devices are Pb-Free, Halogen Free and are RoHS Compliant MARKING DIAGRAM* 1 MC10H643G AWLYYWW A WL YY WW G = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package *For additional marking information, refer to Application Note AND8002/D.
