PAL20L8-10/2PC

Programmable Logic Device Pld Overview

The PAL20L8-10/2PC is a one-time programmable (OTP) Programmable Array Logic (PAL) device manufactured by Vantis. It features a fixed AND-OR array structure with 20 dedicated inputs and 8 outputs. The component operates at a maximum clock frequency of 71.4 MHz with a propagation delay of 10 ns. It supports TTL logic levels and functions within a commercial temperature range of 0°C to 70°C. The device is housed in a 24-pin PDIP package and requires a nominal supply voltage of 5 V.

Programmable Logic Device Pld Feature Summary

• One-time programmable architecture with fixed AND-OR logic array
• High-speed signal processing capability with 10 ns propagation delay
• TTL-compatible input and output logic levels

Programmable Logic Device Pld Applications

• Implementation of complex combinational logic circuits
• Decoding and encoding functions in digital systems
• Address decoding for memory or peripheral interfacing

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix '2PC' against official Vantis documentation to confirm package type and tape-and-reel specifications. Ensure the OTP nature of the device aligns with production requirements, as programming is irreversible. Confirm RoHS compliance status through current manufacturer declarations rather than third-party listings.

Programmable Logic Device Pld Selection Notes

Select this component when a simple, cost-effective solution for fixed logic functions is required without the complexity of reprogrammable devices. The 20-input capacity suits moderate logic density needs. Consider the 10 ns speed for standard timing applications. Note that the OTP characteristic eliminates the need for erasure circuitry but prevents field updates.

Programmable Logic Device Pld Part Context

This part belongs to the classic PAL series of programmable logic devices, representing a foundational technology before the widespread adoption of CPLDs and FPGAs. Vantis, originally part of AMD's PLD division, continues to support these legacy components for industrial and automotive applications requiring long-term availability and stable performance characteristics.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements may include other manufacturers' PAL20L8 variants with identical electrical specifications. Verify logic polarity and output drive strength compatibility. Generic OTP PAL substitutes must match the 20-input/8-output configuration and 10 ns speed grade to ensure functional equivalence.
