SY100EL05ZC

Overview

The SY100EL05ZC is a 2-input differential AND/NAND gate from the ECL logic family, manufactured by Microchip Technology. It operates within a supply voltage range of -4.2V to -5.5V and features a propagation delay of 185ps to 390ps at +25°C. The device includes internal 75KΩ input pull-down resistors and clamp circuitry for open inputs. It is housed in an 8-pin SOIC package with a commercial operating temperature range of -40°C to +85°C.

Feature Summary

• Provides high-bandwidth output transitions suitable for AC performance applications
• Features internal 75KΩ input pull-down resistors for stable operation
• Includes clamp circuitry to maintain active states under open input conditions

Applications

• High-speed digital logic circuits requiring differential signaling
• Applications necessitating ultimate AC performance capabilities
• Systems utilizing differential OR/NOR gate configurations via inverted inputs

Procurement Notes

Verify component authenticity through authorized channels as the part originates from Micrel, now part of Microchip. Confirm that the specific ZC suffix corresponds to the commercial grade variant with Sn-Pb lead finish. Ensure compatibility with existing PCB footprints designed for the 8-pin SOIC (Z8-1) package before procurement.

Selection Notes

Select this component when differential AND/NAND functionality is required with propagation delays significantly faster than standard E404 devices. Consider the -4.2V minimum supply voltage requirement for the 100EL series compared to the -4.75V requirement for the 10EL series. Verify that the commercial temperature range meets system environmental specifications.

Part Context

This device belongs to the SY10/100EL05 product line, which serves as a functional equivalent to the legacy E404 devices but offers enhanced performance metrics. The 100EL variant specifically supports a wider supply voltage range starting at -4.2V, distinguishing it from the 10EL counterpart while maintaining identical logical operations and pinouts.

Replacement Considerations

Direct replacements include the SY10EL05ZC for lower voltage requirements or the SY100EL05ZI for industrial temperature ranges. Verify that substitute packages match the 8-pin SOIC dimensions and that lead finishes are compatible with assembly processes.
