PAL16R8ACNL

Programmable Logic Device Pld Overview

The PAL16R8ACNL is an Over-The-Top (OT) Programmable Logic Device manufactured by Vantis Corporation. It features a PAL-type architecture with 8 dedicated inputs and 8 registered outputs, providing 64 product terms for logic implementation. The device operates at a maximum clock frequency of 25 MHz with a propagation delay of 25 ns. It is housed in a 20-pin Plastic Quad Chip Carrier (PQCC) package, specifically identified as LDCC20,.4SQ, and requires a nominal 5 V power supply. The component is designed for TTL-compatible interfaces.

Programmable Logic Device Pld Feature Summary

• PAL-type architecture with 8 inputs and 8 registered outputs
• 25 ns propagation delay and 25 MHz maximum clock frequency
• 20-pin PQCC (LDCC20,.4SQ) plastic quad chip carrier package
• TTL input/output compatibility with 5 V nominal supply voltage

Programmable Logic Device Pld Applications

• Registered output logic functions requiring synchronous state retention
• Digital systems utilizing TTL-compatible signal levels
• Embedded logic replacement in compact surface-mount designs

Programmable Logic Device Pld Procurement Notes

Verify the specific manufacturer source, as Vantis Corporation assets have undergone corporate transitions. Confirm that the PQCC package variant matches the required footprint for PCB layout. Check RoHS compliance status, as older PLD variants may not meet current environmental standards. Ensure the registered output configuration aligns with the target system timing requirements.

Programmable Logic Device Pld Selection Notes

Select this part when a registered output is required for 8-bit data paths or control signals. The 25 ns delay suits moderate-speed digital applications. Compare against the PAL16R8BNC if a DIP package is preferred, or the PAL16R4B if fewer inputs are sufficient. Verify that the 5 V operating voltage matches the system power rails.

Programmable Logic Device Pld Part Context

This component belongs to the PAL16 family of programmable logic devices, which were widely used before the prevalence of complex FPGAs. The 'AC' suffix typically denotes the speed grade, while 'NL' indicates the lead-free or specific packaging variant within the Vantis lineup. These devices serve as direct replacements for standard fixed-function logic gates in legacy designs.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with PAL16R8 series devices from other manufacturers only if pinout and electrical specifications are identical.
