Product details
Overview
SY10EL01ZC from Micrel is a 4-input ECL OR/NOR gate IC operating at –5.2 V VEE with 230 ps typical propagation delay, 225 ps typical output rise/fall time, and internal 75 kΩ input pull-down resistors-used in high-speed clock distribution and logic decision circuits in telecom line cards.
For engineers reviewing the SY10EL01ZC datasheet, SY10EL01ZC pinout, SY10EL01ZC application, or SY10EL01ZC equivalent, key selection criteria include ECL-compatible input thresholds, dual-output (Q and Q̅) availability, SOIC-8 package compatibility, and commercial-temperature-range DC/AC performance under –5.2 V supply.
Technical Context
The SY10EL01ZC implements true ECL logic with differential output structure (Q and Q̅), supporting both OR and NOR functions via complementary outputs. It operates with VEE = –5.2 V (min –4.75 V, max –5.5 V) and VCC tied to GND, requiring negative supply biasing and termination to –2 V for proper signal integrity.
Its AC performance is characterized across temperature (–40°C to +85°C), with propagation delay bounded between 130 ps (typ) and 330 ps (max) at +25°C, and output transitions specified from 20% to 80% for rise/fall times-enabling reliable operation in >1 GHz edge-rate systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ECL (Emitter-Coupled Logic), compatible with 10K/100K series level-shifting interfaces |
| Propagation Delay (tPD) | 230 ps typical at +25°C - enables sub-500 ps logic decision cycles in pipelined data paths |
| Output Rise/Fall Time (tr/tf) | 225 ps typical (20%–80%) - supports clean signal edges up to ~1.8 GHz fundamental frequency |
| Supply Voltage (VEE) | –4.75 V to –5.5 V - requires regulated negative rail; VCC = GND configuration |
| Input Pull-down Resistor | 75 kΩ internal - eliminates need for external biasing on unused inputs in point-to-point routing |
| Operating Temperature | 0°C to +70°C (Commercial) - validated for stable timing in non-extended-environment telecom chassis |
Pinout & Package
Package: 8-pin SOIC (Z8-1), 0.150" wide, Sn-Pb lead finish, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D3 | Active-low ECL data inputs | Accept standard ECL logic levels (–1.3 V HIGH, –2.0 V LOW); internally pulled down to VEE |
| Q | True output (OR function) | Complementary to Q̅; sourced from emitter-follower stage with 50 Ω dynamic impedance |
| Q̅ | Inverted output (NOR function) | Provides simultaneous OR/NOR result without external inversion; matched delay to Q |
| VCC | Ground reference terminal | Connected to system GND; not a power input - all current flows through VEE |
| VEE | Negative supply rail | Primary power connection; supplies bias current for all transistors; must be low-noise and well-decoupled |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary outputs (Q/Q̅) | Enables single-gate implementation of both OR and NOR logic, reducing board area and interconnect skew |
| 230 ps typical propagation delay | Meets setup/hold timing budgets in 2.5 Gbps serial link control planes and SONET framers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL OR/NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SY100EL01ZC | Higher drive strength (20 mA vs 14 mA), wider VEE range (–4.2 V to –5.5 V), higher IEE (16 mA typ) | Better suited for driving longer traces or multiple loads; less sensitive to VEE droop | Select SY100EL01ZC when fanout >2 or trace length >3 inches is required; SY10EL01ZC preferred for lowest power in compact layouts |
| MC10EL01DR2 | Same pinout, identical AC specs, but ON Semiconductor branding; Pb-free NiPdAu finish standard | No functional change; RoHS-compliant by default; same thermal profile for reflow | Choose MC10EL01DR2 for new designs requiring lead-free compliance without layout revision |
Compared with SY100EL01ZC, the SY10EL01ZC offers lower supply current and tighter propagation delay consistency across voltage, while MC10EL01DR2 provides identical timing with guaranteed Pb-free construction-making SY10EL01ZC optimal for cost-sensitive commercial telecom modules where Sn-Pb assembly remains acceptable.

FAQ
What logic functions does the SY10EL01ZC implement?
The SY10EL01ZC implements both 4-input OR and NOR logic functions simultaneously via its complementary Q and Q̅ outputs. Its internal ECL structure produces true OR at Q and inverted (NOR) output at Q̅ with matched propagation delay. This dual-output capability eliminates the need for external inverters in applications requiring both functions, and is explicitly confirmed in the Micrel datasheet Rev. G functional description and truth table.
What is the correct supply configuration for SY10EL01ZC?
The SY10EL01ZC requires VEE = –4.75 V to –5.5 V (typically –5.2 V) and VCC connected directly to GND - it does not use VCC as a positive supply. All current flows from VEE through internal transistors to GND. Termination networks must reference –2 V, and unused inputs should rely on the internal 75 kΩ pull-downs to VEE. This configuration is defined in the DC Electrical Characteristics table and Package Diagram of the SY10EL01ZC datasheet.
Is SY10EL01ZC pin-compatible with SY100EL01ZC?
Yes, SY10EL01ZC and SY100EL01ZC share identical pinout, package (Z8-1 SOIC), and terminal functions - both have D0–D3, Q, Q̅, VCC, and VEE on the same pins. However, SY100EL01ZC draws higher supply current (16 mA vs 14 mA typ) and supports a wider VEE range (–4.2 V min), so direct substitution is electrically safe but may affect power budget and noise margin in marginal designs.
Does SY10EL01ZC require external pull-down resistors on unused inputs?
No, SY10EL01ZC includes internal 75 kΩ pull-down resistors on all D0–D3 inputs, as stated in the Features section and confirmed in the DC Electrical Characteristics table. These resistors tie unused inputs to VEE, ensuring defined logic LOW states without external components - a key differentiator from earlier E101-series gates and explicitly documented for SY10EL01ZC in the March 2006 datasheet Rev. G.
What is the maximum operating temperature range for SY10EL01ZC?
The SY10EL01ZC is rated for commercial temperature operation from 0°C to +70°C, as specified in the Package/Ordering Information table under "Operating Range" for part number SY10EL01ZC. This differs from the industrial-grade SY10EL01ZI (–40°C to +85°C) and is validated by AC parameter limits tabulated only across 0°C to +85°C - with full spec compliance guaranteed from 0°C onward.
