The MC10H/100H646 is a single supply, low skew translating 1:8 clock driver. Devices in the ON Semiconductor H646 translator series utilize the 28-lead PLCC for optimal power pinning, signal flow through and electrical performance. The single supply H646 is similar to the H643, which is a dual supply 1:8 version of the same function. The H646 was designed specifically to drive series terminated transmission lines. Special techniques were used to match the HIGH and LOW output impedances to about 7.0 W. This simplifies the choice of the termination resistor for series terminated applications. To match the HIGH and LOW output impedances, it was necessary to remove the standard IOS limiting resistor. As a result, the user should take care in preventing an output short to ground as the part will be permanently damaged.
