Product details
Overview
SY10EP01VZI from Micrel is a 4-input ECL OR/NOR gate operating at 3.3V or 5V supply, delivering 230ps typical propagation delay, 3GHz bandwidth, and integrated 75kΩ input pulldowns. It serves as a high-speed logic building block in clock distribution, data multiplexing, and signal combining circuits within industrial-grade telecom and test equipment.
For engineers reviewing the SY10EP01VZI datasheet, SY10EP01VZI pinout, SY10EP01VZI application, or SY10EP01VZI equivalent, key selection factors include its industrial temperature range (–40°C to +85°C), differential ECL output swing (–1.935V to –0.885V), and compatibility with both SOIC and MSOP packages for layout flexibility in high-frequency designs.
Technical Context
The SY10EP01VZI implements true ECL logic with complementary Q and /Q outputs, supporting both OR and NOR functions via active-high or active-low interpretation of inputs D0–D3. Its internal pulldown resistors ensure defined LOW default on Q when inputs are open.
It operates across dual supply configurations: VCC = 0V / VEE = –3.0V to –5.5V, or VCC = 3.0V to 5.5V / VEE = 0V. Output loading is specified into 50Ω to VCC – 2.0V, maintaining consistent voltage thresholds across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 230ps typical (D→Q), enabling sub-nanosecond timing control in critical paths |
| Max Toggle Frequency | 3GHz (functional guarantee), suitable for RF sampling and high-speed serial data routing |
| Supply Options | 3.3V or 5V operation with dual-rail ECL biasing (VCC/VEE) |
| Input Pulldown | 75kΩ internal resistors prevent floating inputs without external components |
| Output Swing | –1.935V to –0.885V (differential), compatible with standard ECL-terminated systems |
| Temp Range | –40°C to +85°C industrial grade, validated for sustained operation in base station and instrumentation environments |
Pinout & Package
SY10EP01VZI is supplied in an 8-pin SOIC package (Z8-1 footprint), with gull-wing leads and Sn-Pb finish. Pin spacing is 1.27mm, body width 3.9mm, and total length 4.9mm - compatible with standard SOIC-8 reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D3 | ECL Data Inputs | Active-low referenced inputs accepting –1.935V to –0.885V logic levels; internally pulled down to VEE |
| Q | True Output | Complementary ECL output; goes LOW when all inputs are LOW (OR function) |
| /Q | Inverted Output | 180° phase-opposed to Q; supports differential signaling and noise rejection |
| VCC | Positive Supply Rail | Connect to 0V (for negative ECL) or +3.3V/+5V (for positive-referenced ECL mode) |
| VEE | Negative Supply Rail | Connect to –3.0V to –5.5V (negative ECL) or 0V (positive-referenced mode) |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed OR/NOR Logic | Single-gate implementation of 4-input Boolean OR/NOR with <250ps max tPD across temperature |
| Dual-Supply Flexibility | Supports both traditional negative-rail (VEE = –5.5V) and modern positive-rail (VCC = 3.3V/5V) ECL configurations |
| Open-Input Default Behavior | Q output asserts LOW when all D0–D3 are unconnected - eliminates need for external termination in unused-input cases |
| Industrial Temperature Rating | Guaranteed DC and AC performance over –40°C to +85°C, including skew ≤20ps and VOL/VOH stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-input ECL OR/NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SY100EP01VZI | Enhanced version with improved skew (≤15ps) and lower power (IEE ≤25mA typ), same pinout and logic function | Preferred for new designs requiring tighter timing budgets or lower thermal load in dense PCB layouts | Select SY100EP01VZI when sub-15ps skew or <25mA IEE is required; otherwise SY10EP01VZI remains fully functional |
| MC100EP01DTG | Pin-compatible 4-input OR/NOR gate from ON Semiconductor; identical Z8-1 SOIC package and ECL voltage levels | Validated in automotive-qualified systems; wider availability in tape-and-reel formats for high-volume production | Choose MC100EP01DTG for AEC-Q100-compliant designs or where distributor stock depth favors ON Semi channels |
Compared with SY100EP01VZI and MC100EP01DTG, the SY10EP01VZI offers proven industrial reliability at lower cost but lacks enhanced skew specs and automotive qualification - making it optimal for cost-sensitive, non-automotive high-speed logic where legacy compatibility is prioritized.

FAQ
What is the recommended power supply configuration for SY10EP01VZI in a 3.3V system?
The SY10EP01VZI supports two valid supply modes: for 3.3V operation, set VCC = +3.3V and VEE = 0V; all input/output voltage levels shift accordingly, with VIH/VIL referenced to VCC. This configuration maintains full AC performance and matches standard 3.3V ECL logic families. The SY10EP01VZI datasheet specifies DC and AC parameters under this condition, including VOH = –0.820V (min) and VOL = –1.630V (max) at TA = +25°C.
Does SY10EP01VZI require external pull-down resistors on its D0–D3 inputs?
No, the SY10EP01VZI integrates 75kΩ internal pulldown resistors on each D0–D3 input, ensuring a defined LOW state when inputs are left unconnected. This eliminates the need for external resistors in unused-input scenarios and simplifies board layout. The SY10EP01VZI truth table confirms Q defaults LOW when all inputs are open, a behavior directly enabled by these internal terminations.
Can SY10EP01VZI be used as a drop-in replacement for EL01 or E101 devices?
Yes, the SY10EP01VZI is functionally equivalent to the EL01 and E101 quad OR/NOR gates per Micrel's documentation, sharing identical logic function, pinout, and electrical specifications. However, the SY10EP01VZI is a single-gate device in SOIC/MSOP, whereas E101 is quad in 16-pin packages - direct replacement applies only at the per-gate level with appropriate package adaptation. The SY10EP01VZI retains full compatibility with legacy ECL Pro™ system designs.
What is the maximum output current rating for SY10EP01VZI's Q and /Q pins?
The SY10EP01VZI specifies ±50mA continuous output current per Q and /Q pin, with ±100mA surge capability for short durations. These ratings apply under absolute maximum conditions and assume proper 50Ω termination to VCC – 2.0V. Exceeding ±50mA continuously may cause thermal derating or VOH/VOL shift; the SY10EP01VZI is intended for driving controlled-impedance transmission lines, not heavy capacitive loads.
Is SY10EP01VZI compliant with RoHS or lead-free assembly requirements?
The SY10EP01VZI uses Sn-Pb lead finish and is not RoHS-compliant; however, Micrel offered Pb-free variants (e.g., SY10EP01VZG) with NiPdAu plating. For new designs, SY10EP01VZI should be replaced with a Pb-free alternative unless legacy compliance or solder-profile constraints mandate Sn-Pb. The SY10EP01VZI datasheet explicitly recommends Pb-free packages for new designs, confirming its non-RoHS status.
