Precision Edge® PrecisionSY100HA643 Edge® SY100HA643 DUAL SUPPLY OCTAL ECL-TO-TTL Micrel, Inc. FEATURES ■ ECL/TTL version of popular ECLinPS™ E111 ■ 400ps within device skew Precision Edge® ■ 800ps part-to-part skew ■ Latch DESCRIPTION ■ Differential internal design ■ VBB output 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. ■ 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 BLOCK DIAGRAM Q0 PIN NAMES Q1 Q2 Q3 D D D VBB TTL OUTPUTS Q LEN Q4 EN Pin Function OGND TTL Output Ground (0V) OVTTTL Output VCC (+5.0V) IGND Internal TTL GND (0V) IVT Internal TTL VCC (+5.0V) VEE ECL VEE (-5.2/-4.5V) VCCE ECL Ground (0V) D, D Signal Input (ECL) VBB VBB Reference Output Q0 - Q7 Signal Outputs (TTL) EN Enable Input (ECL) LEN Latch Enable Input (ECL) Q5 Q6 Q7 Precision Edge is a registered trademark of Micrel, Inc.
