20 ns propagation delay — what it buys on the bus
The ATF22V10BQL-20PC is a 22V10-architecture EE PLD from Microchip with a 20 ns pin-to-pin propagation delay across 10 macrocells.
Microchip no longer manufactures the ATF22V10BQL-20PC in its original form. Every unit we quote is sourced against your specific quantity, with the date-code and marking traceability checked before shipment — the same forensic screen any gray-market PLD should pass.
Through-hole DIP — footprint and rework fit
The 24-pin DIP package (0.300 inch body width, 7.62 mm) with through-hole mounting is a legacy footprint that still appears on industrial control cards and retrofit boards. The 5V-only I/O supply means no level translation on a 5 V backplane.
10 macrocells — logic capacity for glue and state machines
Ten macrocells, each configurable as registered or combinatorial output, give the 22V10 architecture enough room for a handful of address decoders, a small state machine, or bus-arbitration logic. The EE PLD programmable type means the device can be erased and reprogrammed in a standard programmer — no UV eraser, no one-time-programming penalty. If your design needs more than 10 registered outputs, you are looking at a larger 22V10 variant or a CPLD with more macrocells.
