MC10H643: 1:8 Clock Driver

The MC10H/100H643 is a dual supply, low skew translating 1:8 clock driver. Devices in the H600 translator series utilize the 28-lead PLCC 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 48mA TTL output stage, with AC performance specified into a 50pF 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 is compatible with MECL 10H ECL logic levels. The 100H version is compatible with 100K levels.
