Product details
Overview
SY10EL04ZC-TR from Micrel is a 2-input ECL AND/NAND gate in 8-pin SOIC (Z8-1) package, featuring 240 ps typical propagation delay, 225 ps typical output rise/fall time (20%–80%), and internal 75 kΩ input pull-down resistors. It operates with VEE = –5.2 V and supports high-speed timing-critical logic in telecom clock distribution and data path steering.
For engineers reviewing the SY10EL04ZC-TR datasheet, SY10EL04ZC-TR pinout, SY10EL04ZC-TR application, or SY10EL04ZC-TR equivalent, key selection criteria include ECL-compatible voltage swing (–5.2 V VEE), sub-300 ps AC performance, SOIC-8 thermal and layout compatibility, and industrial-grade temperature range support up to +85°C.
Technical Context
The SY10EL04ZC-TR implements dual 2-input ECL logic gates with separate AND and NAND outputs on the same die. Its differential ECL interface requires VCC tied to GND and VEE biased at –4.75 V to –5.5 V, enabling noise-immune operation in high-frequency digital systems.
It uses internal 75 kΩ pull-down resistors on D0 and D1 inputs, eliminating external biasing components. Output transition times remain stable across –40°C to +85°C, with propagation delay variation ≤165 ps over temperature and voltage.
Key Specifications

|---|---|
| Propagation Delay (tPD) | 240 ps typical - enables <1 GHz toggle rate in synchronous logic paths |
| Output Rise/Fall Time (tr/tf) | 225 ps typical (20%–80%) - supports clean edge integrity in >500 MHz signal routing | Supply Voltage (VEE) | –4.75 V to –5.5 V - requires negative rail regulation; VCC = GND |
| Input Pull-down Resistor | 75 kΩ internal - eliminates need for external bias resistors on D0/D1 |
| Operating Temperature | –40°C to +85°C - qualified for industrial environment deployment |
| Package | 8-pin SOIC (Z8-1, .150" wide) - standard footprint compatible with automated assembly |
Pinout & Package
8-pin SOIC (Z8-1) package with gull-wing leads, 1.27 mm pitch, and standard JEDEC MS-012AC outline. Thermal resistance θJA ≈ 120°C/W (JEDEC Std 51-2, still air).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connect - must be left floating or grounded per layout best practice |
| 2 | D0 | First data input - ECL-compatible, internally pulled down to VEE |
| 3 | D1 | Second data input - ECL-compatible, internally pulled down to VEE |
| 4 | NC | No connect - must be left floating or grounded per layout best practice |
| 5 | VCC | Ground reference terminal - tied directly to system GND (0 V) |
| 6 | Q | AND output - active-high ECL output referenced to VEE |
| 7 | VEE | Negative supply rail - –4.75 V to –5.5 V; primary power return path |
| 8 | Q̅ | NAND output - active-low ECL output, complementary to Q |
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 |
|---|---|---|---|
| SY100EL04ZC-TR | Higher IEE (16 mA typ vs. 14 mA), wider VEE range (–4.2 V to –5.5 V), identical pinout and AC specs | Better suited for low-noise, low-impedance VEE rails; slightly higher static power | Select when VEE regulation tolerance exceeds ±0.25 V or when lower input threshold sensitivity is required |
| MC100EL04DTG | Same function, 8-pin TSSOP package (4.4 mm × 3 mm), 250 ps tPD typ, Pb-free only | Smaller footprint and improved thermal performance; not SOIC drop-in without board rework | Choose for space-constrained designs where SOIC-8 reflow compatibility is not mandatory |
Compared with SY100EL04ZC-TR, the SY10EL04ZC-TR offers lower quiescent current and tighter VEE min specification, while MC100EL04DTG trades package size for thermal efficiency-neither is pin-compatible without layout revision.

FAQ
What is the recommended power supply configuration for SY10EL04ZC-TR?
The SY10EL04ZC-TR requires VCC connected to system ground (0 V) and VEE biased between –4.75 V and –5.5 V. A well-decoupled –5.2 V rail is recommended for optimal AC performance. The device draws ~14 mA typical supply current. Do not float VCC or reverse-bias VEE beyond absolute maximum ratings.
Does SY10EL04ZC-TR require external pull-up or pull-down resistors on its inputs?
No. The SY10EL04ZC-TR integrates 75 kΩ internal pull-down resistors on both D0 and D1 inputs, eliminating the need for external biasing components. This simplifies layout and ensures defined logic states during power-up or tri-state conditions.
What is the function of Pin 1 and Pin 4 on SY10EL04ZC-TR?
Pin 1 and Pin 4 of the SY10EL04ZC-TR are no-connect (NC) terminals. They must be left unconnected or tied to ground per PCB design best practices-never driven or used as signal paths. Their presence maintains mechanical symmetry in the SOIC-8 package.
Can SY10EL04ZC-TR drive 50 Ω transmission lines directly?
Yes-the SY10EL04ZC-TR outputs are designed for 50 Ω terminated loads. With VEE = –5.2 V and proper termination to VTT (typically –2 V), it delivers full ECL-compatible voltage swing (≈800 mV) and meets specified 225 ps rise/fall times into 50 Ω.
Is SY10EL04ZC-TR RoHS compliant?
No-SY10EL04ZC-TR uses Sn-Pb lead finish and is not RoHS compliant. For Pb-free alternatives, consider SY10EL04ZGTR (NiPdAu finish, Pb-free bar-line indicator), which shares identical electrical specs and SOIC-8 footprint.
