Last-time-buy — what the obsolete status means for your BOM
The GAL22V10D-10LPN: For sustainment programs that already carry this order code on the BOM, the remaining supply is limited to existing inventory held through independent distribution channels. Availability is lot-specific and confirmed at RFQ time — no last-time-buy window remains open.
10 ns speed grade — what it buys in a legacy 5 V system
The 10 ns maximum propagation delay (tpd(1)) sets the combinatorial-logic throughput ceiling. In a 5 V backplane running at 50 MHz, this part keeps registered paths within one clock cycle for glue-logic functions like address decoding or state-machine encoding. Ten macrocells with EE PLD programmable type give 22 input pins and 10 I/O macrocells — the classic 22V10 architecture that has been a workhorse in industrial control and telecom line cards since the 1990s.
Package and board-fit — 24-pin DIP legacy footprint
Housed in a 24-DIP (0.300", 7.62mm) through-hole package with a 24-PDIP supplier device package designation. The 0.100-inch pitch and 0.300-inch row spacing match the standard DIP socket footprint used on countless legacy PCB layouts. Operating temperature range is 0°C to 75°C (TA) — commercial grade. This limits the part to indoor, temperature-controlled environments; it is not rated for industrial or automotive extended-temperature duty.
