| Precision Edge(R) Micrel, Inc. DUAL SUPPLY OCTAL ECL-TO-TTL SY100HA643 Precision Edge(R) SY100HA643 FEATURES 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 MC100H643 Higher performance than H643 versions Industrial temperature availability Available in 28-pin PLCC package Precision Edge(R) 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 singlesupply 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.
