PAL16L8ACNL

Programmable Logic Device Pld Overview

The PAL16L8ACNL is a Programmable Logic Device (PLD) IC manufactured by Vantis. It features an architecture based on a programmable AND array driving a fixed OR array, utilizing TTL logic levels. The device contains 8 macrocells and supports 8 inputs with registered outputs. It is housed in a 20-pin Plastic Quad Chip Carrier (PQCC) package. Key electrical specifications include a maximum operating frequency of 25 MHz and a standard supply voltage of 5 V. The component is designed for high-speed digital logic applications requiring custom product term generation.

Programmable Logic Device Pld Feature Summary

• Features a programmable AND array combined with a fixed OR array to generate custom logic functions.
• Provides registered output capability through its 8 macrocells for synchronous logic design.
• Supports TTL input logic levels for compatibility with standard digital interfaces.

Programmable Logic Device Pld Applications

• Implementation of complex combinational and sequential logic circuits
• Replacement of discrete gate logic in digital systems
• Custom state machine design using registered outputs

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'ACNL' against the manufacturer's current production status, as legacy PLDs may have limited availability or require confirmation of active manufacturing support from Vantis. Ensure the 20-pin PQCC package form factor matches the target PCB footprint requirements. Confirm that the 5V TTL interface aligns with the system's voltage domains before procurement.

Programmable Logic Device Pld Selection Notes

Select this component when a small-scale PLD with registered outputs is required for logic replacement. The 8-macrocell capacity suits simple control logic or address decoding tasks. Consider the 25 MHz speed limit for timing constraints. The PQCC package requires appropriate surface-mount assembly processes. Evaluate if the fixed OR array structure meets the specific boolean function complexity needs of the application.

Programmable Logic Device Pld Part Context

This part belongs to the PAL16L8 family of Advanced Micro Devices/Vantis programmable logic devices. These devices were widely used in the 1980s and 1990s for replacing medium-scale integration logic chips. The ACNL variant specifically denotes the plastic quad chip carrier package and commercial temperature range specifications within the broader PAL16L8 series lineup.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements may include other PAL16L8 variants such as PAL16L8-4JC or PAL16L8-7DC, provided the speed grade and package type are compatible. Verify that any substitute maintains the registered output functionality and TTL input thresholds. Cross-reference with Vantis or authorized distributors for current equivalent part numbers.
