GAL20V8B-15LD/883

An end-of-life programmable logic device from Lattice Semiconductor, the GAL20V8B-15LD/883 is an E2CMOS Generic Array Logic device delivering 20V8 macrocell architecture in a hermetic ceramic dual-in-line package (CDIP). Processed to MIL-STD-883 Class B screening, this device incorporates 20 input/output macrocells across 24 pins, with a propagation delay of 15 nanoseconds and electrically erasable reprogrammability. The GAL20V8B family’s industry-standard architecture enables it to replace multiple fixed-function logic ICs, integrating combinational and registered logic into a single, high-reliability component suited for military and aerospace systems where environmental ruggedness and deterministic timing are essential.

Now an officially discontinued part, the GAL20V8B-15LD/883 remains critical for sustaining defense, avionics, and high-reliability industrial equipment that were qualified around this specific device. Its MIL-STD-883 compliance, hermetically sealed CDIP construction, and wide operating temperature range make it ideal for long-deployment programs such as radar signal processing, flight control interfaces, and mission computer glue logic where redesign and system requalification would impose prohibitive cost and schedule delays. ZZX Electronics sources legacy stock of this obsolete device with full date-code traceability, providing a dependable path for maintenance, repair, and life-of-type program requirements without necessitating board layout changes or new part qualification cycles.
