DESCRIPTION
The SY100HA643 is an enhanced dual supply, low skew translating 1:8 clock driver. Devices in the Micrel H600 translators series utilize the 28-lead PLCC for optimal power pinning, signal flow through and electrical performance. The dual-supply HA643 is similar to the H641, which is a single supply 1:9 version of the same function, with higher performance than the H643 versions.
