PAL20L8ACNL

Programmable Logic Device Pld Overview

The PAL20L8ACNL is a Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It belongs to the OT PLD family and utilizes TTL technology. The component features 16 dedicated inputs and 8 outputs, with all output functions configured as combinatorial. It operates at a maximum clock frequency of 25 MHz and has a propagation delay of 25 ns. The device is housed in a 20-pin PQCC package, supports surface mount assembly, and requires a nominal 5 V power supply.

Programmable Logic Device Pld Feature Summary

• TTL-based PAL architecture with 16 inputs and 8 combinatorial outputs
• 25 ns propagation delay supporting up to 25 MHz operation
• 20-lead Plastic Quad Chip Carrier (PQCC) surface-mount package

Programmable Logic Device Pld Applications

• Combinatorial logic implementation in digital systems
• Address decoding circuits
• Bus control logic

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer designation as Vantis Corporation during sourcing. Confirm the package type is PQCC20 and that the electrical characteristics match the 25 ns specification. Ensure the input/output configuration aligns with the 16-input, 8-output layout required for the specific application design.

Programmable Logic Device Pld Selection Notes

Select this component when a TTL-compatible PAL with 16 inputs and 8 combinational outputs is required. The 25 ns speed class suits moderate-frequency digital designs. Consider the PQCC20 package constraints for PCB layout if surface mounting is preferred over through-hole alternatives like PDIP.

Programmable Logic Device Pld Part Context

This part is part of the PAL series from Vantis, which includes various configurations of programmable logic devices. The PAL20L8ACNL specifically provides a fixed function set of 16 inputs and 8 outputs, distinguishing it from registered or mixed-output variants within the same product line.

Programmable Logic Device Pld Replacement Considerations

Check for direct equivalents such as the PAL20L8AC from other manufacturers like AMD or National Semiconductor, ensuring pinout and electrical specifications are compatible.
