Frequently Asked Questions
What propagation delay and clock frequency does the GAL22V10D-15LP support for digital logic designs?
The GAL22V10D-15LP offers a maximum propagation delay of 15 ns and supports clock frequencies up to 55.5 MHz. These specifications make it a capable choice for high-speed glue logic, address decoding, and state machine applications in 24-pin DIP board designs.
How many macrocells and inputs does the GAL22V10D-15LP provide for combinational logic implementation?
The GAL22V10D-15LP integrates 10 macrocells with a shared input/clock architecture and 22 total inputs, of which 11 are dedicated inputs and 10 are bidirectional I/O lines. This capacity supports a wide range of PAL-type combinational and registered logic configurations in a single 24-pin DIP package.
When should an engineer choose the GAL22V10D-15LP over a GAL22V10D with a slower speed grade?
Engineers should select the GAL22V10D-15LP when the design requires a 15 ns propagation delay to meet setup and hold timing margins in systems operating above 40 MHz. Slower speed grades such as the 25 ns variant may introduce timing violations in bus interfaces or synchronous state machines where the GAL22V10D-15LP's 55.5 MHz rated performance is necessary.
