PAL20R8-7PC

Programmable Logic Device Pld Overview

The PAL20R8-7PC is an EE PLD manufactured by Vantis Corporation, housed in a 20-pin PDIP package. It features 16 dedicated inputs and 8 registered outputs, utilizing CMOS technology with a propagation delay of 7.5 ns. The device operates at a maximum clock frequency of 125 MHz and requires a nominal supply voltage of 5 V. Designed for commercial temperature ranges, it supports up to 70°C operation. The component integrates macrocell output functions within a plastic/epoxy rectangular in-line form factor, suitable for standard through-hole mounting applications.

• Address decoding logic

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin, as Vantis assets were acquired by Lattice Semiconductor. Confirm the specific suffix '7PC' corresponds to the 7.5 ns speed grade and PDIP package. Check RoHS compliance status, as older PAL devices may not meet current environmental standards. Ensure the registered output configuration matches the target design requirements.

Programmable Logic Device Pld Selection Notes

Select this part when a registered PAL architecture with 16 inputs and 8 outputs is required. The 7.5 ns delay suits moderate-speed digital designs. Compare against the PAL20R8ACNL for QCC20 packaging options if surface mount is preferred. Verify that the 5V CMOS interface aligns with the system's logic levels and power supply constraints.

Programmable Logic Device Pld Part Context

This component belongs to the classic PAL (Programmable Array Logic) family, specifically the PAL20R8 variant which provides registered outputs. Vantis Corporation produced these devices before their intellectual property was transferred to other semiconductor entities. The PAL20R8-7PC represents a high-speed CMOS version of the traditional TTL-based PAL architectures.

Programmable Logic Device Pld Replacement Considerations

Lattice Semiconductor offers compatible GAL or CPLD replacements. Cross-reference with PAL20R8 variants from National Semiconductor or Monolithic Memories for pin-compatible alternatives. Verify electrical characteristics match the 7.5 ns delay requirement.
