| DUAL SUPPLY OCTAL ECL-TO-TTL FEATURES s s s s s s s s s s s s s ECL/TTL version of popular ECLinPSTM E111 400ps within device skew 800ps part-to-part skew Latch Differential internal design VBB output Dual supply Reset/Enable Multiple TTL and ECL power/ground pins Fully compatible with Motorola MC100H643 Higher performance than H643 versions Industrial temperature availability Available in 28-pin PLCC package ClockWorksTM SY100HA643 DESCRIPTION The SY100HA643 is an enhanced dual supply, low skew translating 1:8 clock driver. Devices in the Micrel-Synergy 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. The device features a 48mA TTL output stage, with AC performance specified into a 20pF 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 100HA643 is compatible with 100K ECL logic levels.

Within-Device skew defined as identical transitions on similar paths through a device. 2. Pulse width is defined relative to 1.5V measurement points on the output waveform. 3. Frequency at which output levels will meet a 0.8V to 2.0V minimum swing. 4. The fMAX value is specified as the minimum guaranteed maximum frequency. Actual operational maximum frequency may be greater.
