AMPAL22V10AJC

Overview

The AMPAL22V10AJC is a PAL-type programmable logic device manufactured by AMD (Advanced Micro Devices). It features a ceramic LCC-28 package with 28 pins. The device operates with TTL input levels and has a maximum propagation delay of 15ns, supporting a clock frequency up to 40 MHz. It includes 22 inputs and 10 outputs, with 11 dedicated inputs. The component is not RoHS compliant.

Feature Summary

• PAL-type architecture with 132 product terms
• 22 inputs and 10 outputs in a 28-pin LCC package
• 15ns propagation delay and 40 MHz max clock frequency
• TTL-compatible input logic levels

Applications

• Digital logic replacement
• State machine implementation
• Address decoding

Procurement Notes

Verify the manufacturer as AMD (Advanced Micro Devices) and confirm the specific suffix 'JC' indicates the ceramic LCC-28 package variant. Ensure compliance requirements are met as the part is non-RoHS. Check for availability of datasheets confirming the 15ns speed grade.

Selection Notes

Select this component when a PAL-type structure with 22 inputs and 10 outputs is required. The 15ns delay suits applications needing moderate speed. Verify that the TTL input voltage levels match the system design. Consider the ceramic package for high-reliability environments if necessary.

Part Context

This part belongs to the PAL22V10 family of programmable logic devices from AMD. These devices were widely used in digital systems before the prevalence of complex FPGAs. The AMPAL22V10AJC specifically denotes the accelerated 15ns speed grade in a ceramic leaded chip carrier package.

Replacement Considerations

Direct pin-to-pin replacements may include other PAL22V10 variants from different manufacturers such as Lattice or Atmel, provided they offer compatible electrical characteristics and package dimensions. Verify logic function equivalence carefully.
