The MC10H/100H641 is a single supply, low skew translating 1:9 clock driver. Devices in the H600 translator series utilize the 28-lead PLCC for optimal power pinning, signal flow through and electrical performance.
The device features a 24mA 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 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 V
output is provided in case the user wants to drive the device with a single-ended input. For single-ended use the V
should be connected to the D input and bypassed with a 0.01 F capacitor.
The 10H version of the H641 is compatible with positive MECL 10H logic levels. The 100H version is compatible with positive 100K levels.
