HSP43891GC-30

Overview

The HSP43891GC-30 is a high-performance analog-to-digital converter manufactured by Harris Corporation. It features a sampling rate of 30 MSPS and an input bandwidth of 250 MHz, supporting data rates up to 60 MSPS. The device utilizes a 12-bit resolution architecture with a differential input configuration. It operates within a supply voltage range of +5V for the analog section and ±5V for the digital interface. The component is housed in a ceramic dual in-line package (CDIP) with 28 pins, designed for robust industrial and military applications.

Feature Summary

• High-speed analog-to-digital conversion with wide input bandwidth
• Differential input architecture for improved noise rejection
• Compatible with standard TTL/CMOS logic levels
• Robust ceramic packaging for harsh environments

Applications

• Military radar signal processing systems
• Electronic warfare receivers
• Test and measurement instrumentation
• High-frequency communication transceivers

Procurement Notes

Verify the specific suffix 'GC-30' against official Harris datasheets to confirm pinout compatibility and thermal specifications. Ensure that the procurement source provides traceability documentation, as this component may be subject to export controls or restricted distribution channels due to its historical military application context.

Selection Notes

Select this component when a 12-bit resolution at 30 MSPS is required with a wide 250 MHz analog bandwidth. Consider the CDIP28 package constraints for PCB layout and thermal management. Evaluate power consumption requirements relative to the +5V and ±5V supply rails compared to modern CMOS alternatives.

Part Context

This part belongs to the Harris HSP438xx series of high-speed ADCs, widely used in defense electronics during the late 20th century. Harris Semiconductor was later acquired by Intersil, which subsequently became part of Renesas Electronics. The component represents legacy technology often found in existing military infrastructure maintenance.

Replacement Considerations

Direct pin-compatible replacements are scarce due to proprietary internal architectures. Modern equivalents from manufacturers like Analog Devices or Texas Instruments may offer similar performance but require significant schematic redesign. Verify if the HSP43891G or other variants in the series serve as functional substitutes.
