Overview
The 100124DCQR is a TTL to ECL translator manufactured by National Semiconductor, belonging to the ECL100K series. It functions as a single-channel level shifter designed to convert signals between Transistor-Transistor Logic (TTL) and Emitter-Coupled Logic (ECL) voltage domains. The device operates within an industrial temperature range of -40°C to 85°C. It is supplied in a bulk package configuration.
Feature Summary
- Performs direct logic level translation from TTL input standards to ECL output standards
- Designed for high-speed signal interfacing applications requiring ECL100K performance characteristics
Applications
- Interfacing TTL-based digital systems with ECL-compatible components
- High-speed data handling circuits requiring logic domain conversion
- System designs utilizing ECL100K family components
Procurement Notes
Verify the manufacturer origin, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix 'DCQR' matches the required package and temperature grade. Ensure compatibility with existing ECL100K design specifications before procurement.
Selection Notes
Select this component when a single-channel solution is needed to bridge TTL and ECL logic families. Consider the ECL100K series speed and power trade-offs. Verify that the bulk packaging format aligns with assembly requirements and that the operating temperature range meets environmental constraints.
Part Context
This part belongs to the ECL100K series, which provides high-speed emitter-coupled logic solutions. The 100124DCQR specifically addresses the need for translating lower-voltage TTL signals into the negative-swing ECL format used in high-performance computing and telecommunications infrastructure.
Replacement Considerations
Consult official substitution guides for equivalent translators within the ECL100K family or modern equivalents from Texas Instruments. Verify pinout and electrical parameter compatibility before replacing.
