PAL16R4-7PC

Programmable Logic Device Pld Overview

The PAL16R4-7PC is a Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It features a TTL-compatible interface with 16 inputs and 8 outputs, including 4 registered macrocells. The component operates at a nominal supply voltage of 5V and exhibits a propagation delay of 7.5ns. Packaged in a 20-pin PDIP format, it supports up to 64 product terms per output function. The device is designed for high-speed logic applications within standard industrial temperature ranges.

Programmable Logic Device Pld Feature Summary

• Supports registered output functions via dedicated macrocells
• TTL-compatible input and output logic levels
• Fuse-programmable architecture for custom logic implementation

Programmable Logic Device Pld Applications

• General-purpose digital logic replacement
• State machine implementation
• Address decoding circuits
• Control signal generation

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix '7PC' against the manufacturer's official documentation to confirm package type and speed grade accuracy. Ensure compliance with RoHS directives if required, as historical data indicates potential non-compliance status for older variants. Cross-reference the manufacturer name Vantis with Advanced Micro Devices (AMD) legacy records, as Vantis acquired AMD's PLD business. Confirm pinout compatibility with existing PCB layouts before procurement.

Programmable Logic Device Pld Selection Notes

Select this component when registered outputs are required for synchronous logic designs. The 7.5ns delay suits moderate-speed applications compared to faster PAL variants. Consider the 20-pin DIP package for prototyping or through-hole assembly needs. Evaluate the 4 macrocell count against logic complexity requirements; higher density devices may be necessary for more complex functions.

Programmable Logic Device Pld Part Context

This part belongs to the classic PAL family of programmable logic devices, originally developed by Advanced Micro Devices and later produced by Vantis Corporation after the acquisition of AMD's PLD division. These devices represent a foundational technology in digital design, offering a balance between flexibility and fixed-function performance. The PAL16R4 variant specifically provides registered outputs, distinguishing it from purely combinational PALs.

Programmable Logic Device Pld FAQ

What is the difference between PAL16R4 and PAL16R6?

The PAL16R4 offers 4 registered macrocells, while the PAL16R6 typically provides 6 registered macrocells, allowing for more complex sequential logic implementation.

Is the PAL16R4-7PC compatible with 3.3V logic?

No, the datasheet specifies a nominal supply voltage of 5V. It is designed for TTL logic levels and is not directly compatible with 3.3V systems without level shifting.
