Product details
Overview
SY10EL07ZG from Micrel is a 2-input ECL XOR/XNOR gate operating at –5.2 V VEE with 260 ps typical propagation delay, 225 ps typical output rise/fall time (20%–80%), and internal 75 kΩ input pull-down resistors, used in high-speed clock/data path logic in industrial-grade timing and signal integrity applications.
For engineers reviewing the SY10EL07ZG datasheet, SY10EL07ZG pinout, SY10EL07ZG application, or SY10EL07ZG equivalent, this page delivers verified functional identity, industrial-temperature SOIC-8 package mapping, ECL-level AC performance specs, pin-specific circuit roles, and two validated alternative parts for high-speed differential logic design.
Technical Context
The SY10EL07ZG implements true ECL (Emitter-Coupled Logic) topology with differential inputs and complementary outputs, requiring negative VEE (–4.75 V to –5.5 V) and grounded VCC. It operates across –40°C to +85°C with guaranteed AC performance at all temperatures.
Its dual-output architecture provides simultaneous XOR and XNOR logic on pins 4 and 6, enabling phase comparison, parity generation, and data encoding without external inversion. Input pull-downs eliminate floating node risk in unterminated stubs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tPD (Typ) | 260 ps - enables sub-4 GHz toggle-rate logic decision paths in serial link equalizers and clock recovery circuits |
| tr/tf (Typ) | 225 ps (20%–80%) - supports clean edge transitions for <100 ps jitter budgets in high-speed sampling systems |
| VEE Range | –4.75 V to –5.5 V - mandates negative supply rail design; incompatible with PECL or LVDS biasing schemes |
| Input Pull-down | 75 kΩ - ensures defined logic LOW state on unconnected inputs, eliminating need for external termination |
| Operating Temp | –40°C to +85°C - qualified for industrial environments including base station RF front-ends and test equipment |
| Supply Current | 11–17 mA - fixed current draw independent of switching activity, simplifying power rail decoupling |
Pinout & Package
SY10EL07ZG is housed in an 8-pin SOIC package (Z8-1, 0.150" wide), Pb-free with NiPdAu lead finish and industrial temperature rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | No Connect | Internally unused; must remain unconnected per datasheet - no tie-to-ground or pull-up allowed |
| 2 | D1 Input | Inverting input for XOR/XNOR function; accepts ECL-compatible voltage swing (VEE + 0.9 V to VEE + 1.8 V) |
| 3 | VCC | Ground reference terminal - connected to system GND, not a positive supply |
| 4 | Q Output (XOR) | True output of 2-input XOR function; complementary to pin 6; drives 50 Ω terminated loads |
| 5 | VEE | Negative supply rail (–5.2 V typical); primary current return path and logic reference |
| 6 | Q Output (XNOR) | Inverted output (XNOR) - simultaneous with pin 4; enables single-gate phase comparison |
| 7 | D0 Input | Non-inverting input; referenced to same VEE as D1; differential pair with D1 defines logic state |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous XOR/XNOR Outputs | Eliminates need for external inverter in phase-difference detection and parity check circuits |
| Internal 75 kΩ Input Pull-downs | Prevents undefined states on unterminated inputs - critical for hot-swap and partial-configuration systems |
| 260 ps Propagation Delay (Typ) | Supports >3.5 GHz maximum toggle frequency in cascaded logic chains without added latency |
| ECL-Level AC Performance | Guaranteed 225 ps edge rates across full industrial temperature range - no derating required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input ECL XOR/XNOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SY100EL07ZG | Higher drive strength (13–20 mA IEE), wider VEE range (–4.2 V to –5.5 V), identical pinout and AC specs | Better suited for driving longer transmission lines or multiple fanouts; requires lower |VEE| minimum | Select SY100EL07ZG when load capacitance exceeds 2 pF or when VEE regulation tolerance is >±0.25 V |
| MC100EL07DTG | Same function, SOIC-8, Pb-free NiPdAu finish, but specified for –40°C to +85°C with 275 ps max tPD (vs. 395 ps for SY10EL07ZG) | Onsemi variant with tighter AC min/max spread; slightly higher power consumption (12–18 mA) | Choose MC100EL07DTG for designs requiring tighter propagation delay distribution across temperature and voltage |
Compared with SY10EL07ZG, SY100EL07ZG offers higher drive capability and relaxed VEE lower limit, while MC100EL07DTG provides tighter tPD variation - all three share identical pinout and industrial temperature rating, enabling board-level substitution where drive or timing variance requirements differ.

FAQ
What logic family does the SY10EL07ZG belong to, and what supply voltages does it require?
The SY10EL07ZG is an ECL (Emitter-Coupled Logic) device requiring a negative supply: VEE = –4.75 V to –5.5 V and VCC = 0 V (ground). It is not compatible with PECL, LVDS, or CMOS supply configurations. The SY10EL07ZG uses true ECL topology with internal pull-downs and differential input thresholds referenced to VEE.
Does the SY10EL07ZG have both XOR and XNOR outputs, and how are they assigned on the package?
Yes, the SY10EL07ZG provides simultaneous XOR and XNOR logic outputs. Pin 4 delivers the XOR result, and pin 6 delivers the complementary XNOR output. This dual-output capability is intrinsic to the SY10EL07ZG die design and eliminates external inversion in phase-comparison or parity applications.
Is the SY10EL07ZG pin-compatible with the SY100EL07ZG, and what are the key operational differences?
Yes, the SY10EL07ZG is pin-compatible with the SY100EL07ZG - same Z8-1 SOIC-8 package, identical pin functions, and overlapping temperature range. Key differences: SY100EL07ZG draws up to 20 mA (vs. 17 mA max for SY10EL07ZG) and supports a wider VEE range down to –4.2 V, making it better for marginal supply conditions.
What is the purpose of the NC pins (1 and 8) on the SY10EL07ZG, and can they be tied to ground?
Pins 1 and 8 on the SY10EL07ZG are No Connect (NC) terminals - internally unconnected and electrically isolated. Per Micrel's datasheet, they must remain unconnected; tying them to ground, VEE, or any other node may cause unpredictable behavior or damage. The SY10EL07ZG's functionality is fully defined by pins 2–7 only.
How does the internal 75 kΩ input pull-down resistor affect system design when using the SY10EL07ZG?
The internal 75 kΩ pull-down on each input (D0 and D1) of the SY10EL07ZG ensures a defined LOW state when inputs are unterminated or floating, removing the need for external pull-down resistors in point-to-point or lightly loaded configurations. This simplifies layout and improves reliability in hot-swap or partial-power-down scenarios.
