GAL22V10D-15LD/883

The GAL22V10D-15LD/883 is a high-reliability E2CMOS programmable logic device (PLD) manufactured by Lattice Semiconductor. As a member of the GAL22V10 family, it is supplied in a 24-pin CDIP (Ceramic Dual In-line Package) and leverages electrically erasable CMOS technology to provide in-system reprogrammability, low power consumption, and robust data retention. The device architecture offers 22 inputs and 10 individually configurable output logic macrocells, enabling flexible implementation of combinatorial and registered logic functions such as state machines, address decoding, and glue logic. The -15 speed grade indicates a typical propagation delay of 15 nanoseconds, balancing performance with thermal efficiency in embedded systems. The /883 suffix denotes full compliance with MIL-STD-883, ensuring each unit undergoes rigorous military screening for temperature extremes, mechanical shock, burn-in, and hermeticity, making it suited for mission-critical deployment.

Typical end-use scenarios include defense avionics, satellite payloads, radar and secure communications subsystems, industrial process controllers, and legacy military platforms requiring sustained, radiation-tolerant logic replacement. The component is frequently integrated into ruggedized aerospace electronics where predictable timing and long-term reliability are paramount. From a procurement perspective, the GAL22V10 family is mature, and availability for the MIL-STD-883 screened variant is channeled through specialized distributors of obsolete and high-reliability components. Engineering teams qualifying this part for extended-life programs should account for eventual obsolescence and evaluate lifetime buy strategies or form-fit-function alternatives in advance. The /883 qualification simplifies compliance documentation for government and prime contractor contracts, while the CDIP package supports through-hole assembly flows still prevalent in sustainment, repair, and legacy system retrofits.
