PAL16R8B2CN

Programmable Logic Device Pld Overview

The PAL16R8B-2CN is a registered Output Programmable Logic Device (PLD) manufactured by Vantis Corporation. It utilizes a PAL-type architecture with TTL input compatibility and operates at a nominal 5V supply voltage. The device features 12 inputs and 8 registered outputs, providing 64 product terms for logic implementation. It is housed in a 20-pin Plastic Dual In-line Package (PDIP). The maximum propagation delay is specified at 25ns, corresponding to a maximum clock frequency of 25 MHz. The component is rated for an operating temperature range up to 70°C.

Programmable Logic Device Pld Feature Summary

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer designation as Vantis Corporation, noting that this part number may also appear under legacy AMD or National Semiconductor branding due to industry acquisitions. Confirm the suffix '2CN' corresponds to the 25ns speed grade and commercial temperature range. Check RoHS compliance status, as datasheets indicate this specific variant may not be qualified under current environmental standards.

Programmable Logic Device Pld Selection Notes

Select this component when a registered output configuration is required for synchronous logic designs. The 12-input/8-output pin count suits moderate complexity logic functions. Ensure the design accommodates the 25ns propagation delay and 5V logic levels. Compare against the unregistered PAL16R8 if flip-flops are unnecessary, or consider higher-density SPLDs for complex applications.

Programmable Logic Device Pld Part Context

This device belongs to the standard PAL series of simple programmable logic devices. It represents a generation of fixed-function-like flexibility before the dominance of FPGAs. Vantis Corporation produced these parts following the acquisition of earlier intellectual property from Advanced Micro Devices and National Semiconductor.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include the TI TIBPAL16R8 variants and AMD PAL16R8 equivalents. Verify pinout compatibility and electrical characteristics such as propagation delay and supply voltage when substituting.
