Motorola MC10H641/MC100H641 Single Supply PECL-TTL 1:9 Clock Distribution Chip Datasheet

The MC10H/100H641 is a single supply, low skew translating 1:9 clock driver. Devices in the Motorola 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 VBB output is provided in case the user wants to drive the device with a single-ended input. For single-ended use the VBB should be connected to the D input and bypassed with a 0.01µF capacitor. The 10H version of the H641 is compatible with positive MECL 10H logic levels. The 100H version is compatible with positive 100K levels.

Frequently asked questions

What is the function of the Vpp output?

The Vpp output is provided in case the user wants to drive the device with a single-ended input.

How does the latch operate?

When LEN is LOW (or left open), the latch is transparent, while a HIGH on EN forces all outputs LOW.
