2903ADM/B

Overview

The 2903ADM/B is a four-bit bipolar microprocessor slice manufactured by Rochester Electronics, LLC. It belongs to the 2903A series of specialized integrated circuits designed for bit-slice processing architectures. The component features a DIP-14 package and operates within a temperature range of -55 °C to 125 °C. As a discrete logic slice, it serves as a fundamental building block for constructing custom-width processors.

Feature Summary

• Provides four-bit data processing capability for microprocessor construction
• Supports cascading with other slices to create wider word lengths
• Designed for high-reliability applications requiring robust logic performance

Applications

• Custom microprocessor design using bit-slice architecture
• Industrial control systems requiring flexible processor widths
• Test and measurement equipment logic implementation

Procurement Notes

Verify the specific lot code and date code upon receipt to ensure compliance with project requirements. Confirm that the device matches the original manufacturer specifications provided in the official datasheet. Inspect the ceramic DIP-14 package for physical integrity before integration into circuit boards.

Selection Notes

Select this component when designing systems based on the 2903A bit-slice family. Ensure compatibility with associated control signals such as carry chains and mode select inputs. Evaluate thermal management needs given the extended industrial temperature range capabilities of the hermetically sealed package.

Part Context

This part is distributed by Rochester Electronics, LLC, which specializes in sourcing and supplying obsolete and hard-to-find electronic components. The 2903ADM/B represents a legacy bit-slice technology used in earlier generations of computing and industrial hardware designs.

Replacement Considerations

Compatible substitutes include other variants within the 2903A series or equivalent bit-slice processors from original manufacturers, provided pinout and electrical characteristics remain identical.
