Description

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 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 10H version is compatible with MECL 10H™ ECL logic levels.

The 100H version is compatible with 100K levels.
