10561DM

Overview

The 10561DM is a high-speed ECL decoder/driver from the 10K series manufactured by National Semiconductor. It features inverted outputs and is housed in a ceramic CDIP-16 package. The component operates within a military temperature range of -55°C to 125°C and requires a nominal 5V supply voltage. It utilizes through-hole tin/lead terminals with a 2.54 mm pitch, designed for robust performance in demanding electronic applications.

Feature Summary

• High-speed ECL logic family operation
• Inverted output configuration
• Military-grade temperature rating
• Ceramic dual in-line packaging

Applications

• High-speed digital signal processing systems
• Military communication equipment
• Aerospace control units
• Industrial automation controllers

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific package variant (CDIP) matches the design requirements. Check for RoHS compliance status, noting the tin/lead terminal finish may indicate non-compliant formulations. Ensure the part number suffix corresponds to the correct packaging type before finalizing orders.

Selection Notes

Select this component for applications requiring fast switching speeds characteristic of ECL technology. The ceramic package offers superior thermal stability compared to plastic alternatives. Consider the pin count and inverted output logic levels when designing compatible circuit interfaces. Verify availability through authorized distributors given the legacy status of the original manufacturer.

Part Context

This device belongs to the National Semiconductor 10K series, known for high-performance emitter-coupled logic. The company's semiconductor division was acquired by Texas Instruments, which now manages the product line. The 10561DM represents a specialized decoder/driver solution for critical infrastructure where speed and reliability are paramount.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the same ECL family. Verify electrical characteristics such as propagation delay and power consumption against current designs. Ensure any replacement maintains the required military temperature specifications and ceramic package integrity.
