Product details
Overview
SY10EL04ZI from Micrel is a dual 2-input ECL AND/NAND gate operating at –5.2 V VEE with 240 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 distribution and logic interfacing in industrial telecom timing systems.
For engineers reviewing the SY10EL04ZI datasheet, SY10EL04ZI pinout, SY10EL04ZI application, or SY10EL04ZI equivalent, key selection criteria include industrial-temperature ECL logic compatibility, SOIC-8 package footprint, differential output drive capability, and DC/AC performance under –5.2 V supply conditions.
Technical Context
The SY10EL04ZI implements true ECL (Emitter-Coupled Logic) topology with open-emitter outputs requiring external termination to VCC (GND), supporting both AND and NAND functions via complementary Q and Q̅ outputs on Pins 6 and 8. It operates with VEE = –5.2 V (typical) and VCC = GND, enabling negative-rail logic signaling.
Designed for AC-critical paths, it delivers guaranteed tPD ≤ 395 ps over –40°C to +85°C and tr/tf ≤ 350 ps across temperature, with input thresholds referenced to VEE and internal pull-downs eliminating floating input risk in unterminated configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ECL (Emitter-Coupled Logic), negative-voltage referenced, non-RoHS Sn-Pb lead finish |
| Propagation Delay (tPD) | 240 ps typical (25°C), ≤395 ps max (–40°C to +85°C); enables sub-1 GHz logic timing budgets |
| Output Rise/Fall Time | 225 ps typical (20%–80%), ≤350 ps max; supports clean edge integrity in >2 Gbps serial link interfaces |
| Supply Voltage (VEE) | –4.75 V to –5.5 V; requires stable negative rail regulated to –5.2 V nominal for spec-compliant operation |
| Input Pull-down | 75 kΩ internal; ensures defined LOW state on D0/D1 when unconnected, eliminating need for external biasing |
| Operating Temperature | –40°C to +85°C industrial grade; validated across full range per AC/DC electrical specs |
Pinout & Package
Package: 8-pin SOIC (Z8-1), 0.150" wide body, Sn-Pb lead finish, industrial temperature grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unused; must remain unconnected per datasheet |
| 2 | D0 Input | First data input for AND/NAND function; internally pulled down to VEE via 75 kΩ |
| 3 | D1 Input | Second data input; independent pull-down, compatible with ECL-compatible drivers |
| 4 | No Connect | Internally unused; no routing or loading required |
| 5 | VCC | Ground reference terminal (0 V); used as termination point for open-emitter outputs |
| 6 | Q Output | True AND output (active-HIGH in ECL convention); open-emitter, requires 50 Ω to VCC |
| 7 | VEE | Negative supply rail (–5.2 V nominal); decoupling capacitor required at pin |
| 8 | Q̅ Output | Inverted (NAND) output; complementary to Pin 6, same drive strength and timing |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SY100EL04ZI | Higher drive strength (16 mA vs. 14 mA), wider VEE range (–4.2 V to –5.5 V), higher IEE current (13–20 mA vs. 11–17 mA) | Better suited for driving longer traces or heavier loads; less tolerant of VEE droop below –4.5 V | Select SY100EL04ZI when load capacitance exceeds 2 pF or trace length >5 cm; otherwise SY10EL04ZI offers tighter tPD consistency |
| MC10EL04DR2 | Same pinout, identical AC specs, but ON Semiconductor part with different VEE min (–4.98 V) and no internal pull-downs | Requires external 75 kΩ pull-downs on D0/D1; not drop-in for unmodified SY10EL04ZI designs | Choose MC10EL04DR2 only if sourcing continuity is prioritized and board layout allows adding two 75 kΩ resistors |
Compared with SY100EL04ZI and MC10EL04DR2, the SY10EL04ZI provides optimal balance of low propagation delay variation, built-in input biasing, and industrial-grade thermal stability-making it preferred for fixed-layout, high-reliability telecom and test equipment where design-in longevity matters.

FAQ
What is the recommended power supply configuration for SY10EL04ZI?
The SY10EL04ZI requires VCC = GND and VEE = –5.2 V (nominal), with VEE ranging from –4.75 V to –5.5 V. A low-ESR ceramic capacitor (≥100 nF) must be placed between Pin 7 (VEE) and Pin 5 (VCC) near the device. The SY10EL04ZI does not operate with positive-supply ECL variants or PECL configurations.
Does SY10EL04ZI support both AND and NAND functions simultaneously?
Yes. The SY10EL04ZI provides true AND output on Pin 6 (Q) and complementary NAND output on Pin 8 (Q̅) from the same D0/D1 inputs. Both outputs exhibit matched propagation delay and edge rates, enabling simultaneous use without added skew-critical for differential clock enable or strobe generation.
Are the NC pins on SY10EL04ZI safe to connect to ground or leave floating?
Pins 1 and 4 of the SY10EL04ZI are No Connect and must remain unconnected-neither grounded nor tied to any net. Internal connection is undefined; grounding them may cause unpredictable leakage or noise coupling. PCB layout must ensure no copper or via contacts these pins.
What is the purpose of the internal 75 kΩ pull-down resistors on SY10EL04ZI inputs?
The internal 75 kΩ pull-down resistors on D0 (Pin 2) and D1 (Pin 3) of the SY10EL04ZI ensure a defined logic LOW state when inputs are unconnected or driven by high-impedance sources. This eliminates need for external biasing and prevents metastability in unterminated ECL logic chains.
Can SY10EL04ZI be used in place of SY10EL04ZC in an existing design?
Yes, the SY10EL04ZI is pin- and function-compatible with SY10EL04ZC, differing only in temperature rating (industrial –40°C to +85°C vs. commercial 0°C to +70°C) and VEE tolerance. All AC/DC specifications are tested across the wider range, making SY10EL04ZI a direct upgrade for field-deployed systems requiring extended thermal robustness.
