高性能Impact -X é可编程阵列逻辑电路 HIGH-PERFORMANCE IMPACT-X E PROGRAMMABLE ARRAY LOGIC CIRCUITS
description
The BPAL22V10-10C is a programmable array logic device featuring high speed and functional equivalency when compared to presently available devices. They are implemented with the familiar sum-of-products AND-OR logic structure featuring the new concept “Programmable Output Logic Macrocell”. These IMPACT-X circuits combine the latest Advanced Low-Power Schottky technology with proven titanium tungsten fuses to provide reliable, high-performance substitutes for conventional TTL logic.
These devices contain up to 22 inputs and 10 outputs. They incorporate the unique capability of defining and programming the architecture of each output on an individual basis. Outputs may be registered or nonregistered and inverting or noninverting as shown in the output logic macrocell diagram. The ten potential outputs are enabled through the use of individual product terms.
