AMPAL20L10-20JC

Overview

The AMPAL20L10-20JC is a Programmable Array Logic (PAL) device from the PAL20X10A series, manufactured by Vantis. It features an XOR registered architecture with 24 pins in a DIP package. The component provides 20 input lines and 10 registered output lines. It operates at a maximum propagation delay of 20 nanoseconds. The device utilizes TTL logic levels and includes macrocells for flexible logic implementation. It is designed for high-speed digital applications requiring complex combinational and sequential logic functions within a compact integrated circuit form factor.

Feature Summary

• XOR registered logic architecture for efficient state machine implementation
• High-speed 20ns propagation delay for rapid signal processing
• TTL compatible input and output voltage levels
• 24-pin dual in-line package for through-hole mounting

Applications

• Digital control systems requiring registered outputs
• Address decoding circuits
• Interface adapters between different logic families
• Complex gate replacement in legacy designs

Procurement Notes

Verify the specific suffix '20JC' to ensure correct speed grade and package type. Confirm RoHS status as it may be listed as non-applicable depending on the manufacturing batch. Check moisture sensitivity level classification for proper handling during assembly. Ensure compatibility with existing PCB footprints for the 24-pin DIP configuration before procurement.

Selection Notes

Select this component when a registered PAL solution with 20 inputs and 10 outputs is required. Consider the 20ns delay specification against system timing requirements. Evaluate the XOR registered macrocell structure for suitability in counter or state machine applications. Compare pin count and package style against available space constraints on the target board design.

Part Context

This part belongs to the PAL20X10A series of programmable logic devices. It represents a standard TTL-compatible PLD offering. The series is characterized by its registered outputs and fixed AND plane with programmable OR array. It serves as a bridge between discrete logic gates and more complex CPLDs.

Replacement Considerations

Direct substitutes include other PAL20X10 variants with matching speed grades. Verify pin-to-pin compatibility with alternative manufacturers' equivalents. Ensure logical function equivalence if replacing a programmed device.
