Abstract :
The second generation of the advanced single poly emitter coupled technology (ASPECT-II) has been tailored to fabricate an emitter-coupled-logic (ECL) programmable array logic (PAL) product with maximum specified propagation delay of 2 ns. The device is designed as a programmable AND array driving a fixed OR array and is organized as 16 complementary output functions. Complementary outputs eliminate the need for external inverters and also provide signals that can be used in differential interconnect for situations requiring increased noise immunity. All input pins have on-chip 50-Ω pull-down resistors. A maximum propagation delay of 2 ns at a power dissipation of 1.2 W has been achieved. The logic path of this component has been minimized to three ECL gates in order to achieve the required performance. The product is available in both industry standard ECL 100 K and 10 KH logic families
