MC1038P

Overview

The MC1038P is a high-speed ECL (Emitter-Coupled Logic) component belonging to the Motorola 10K series. It functions as a dual 2-input exclusive-OR gate, providing two independent logic channels within a single package. The device utilizes bipolar technology and features open-emitter outputs designed for direct interfacing with transmission lines or subsequent ECL stages without requiring external pull-up resistors. It is housed in a standard 16-pin plastic Dual In-line Package (PDIP), suitable for through-hole mounting on printed circuit boards. The component operates within a temperature range of -30 °C to +85 °C and requires a negative power supply voltage typical for ECL circuits.

Feature Summary

• Dual independent 2-input Exclusive-OR logic functionality
• High-speed ECL architecture optimized for rapid switching
• Open-emitter output configuration for flexible driving capabilities
• Standard 16-pin PDIP housing for reliable board integration

Applications

• Digital signal processing circuits requiring XOR operations
• High-speed data comparison and parity checking systems
• Clock generation and phase detection modules
• ECL-based arithmetic logic units

Procurement Notes

Verify the specific manufacturer source, as production rights for the 10K series have transitioned between Motorola, ON Semiconductor, and NXP. Confirm that the lead time and availability align with current manufacturing schedules, as legacy ECL components may be subject to limited production runs or obsolescence notices. Ensure the procurement channel provides genuine parts with traceable documentation to guarantee performance reliability in critical applications.

Selection Notes

Select this component when designing systems that mandate ECL logic levels for superior speed performance compared to TTL or CMOS alternatives. The dual-gate configuration allows for efficient space utilization in complex digital designs. Consider the requirement for negative power supplies and impedance matching networks associated with open-emitter outputs during the schematic design phase to ensure signal integrity.

Part Context

The MC1038P is part of the extensive Motorola 10K series of ECL logic devices, established for high-performance computing and telecommunications applications. This series defines a standard pinout and electrical characteristic set for ECL gates, facilitating interoperability among various logic functions such as AND, OR, and XOR gates manufactured under the same family guidelines.

Replacement Considerations

Compatible substitutes include the MC10138P and MC10E138P, which offer identical logical functionality and pin configurations. Verify that any replacement maintains compatibility with the existing -5.2V ECL power supply infrastructure and signal termination requirements.
