Product details
Overview
SY100EL04ZG-TR from Micrel is a dual 2-input AND/NAND ECL gate operating at –4.2 V to –5.5 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 decision circuits in industrial telecom infrastructure.
For engineers reviewing the SY100EL04ZG-TR datasheet, SY100EL04ZG-TR pinout, SY100EL04ZG-TR application, or SY100EL04ZG-TR equivalent, key selection criteria include ECL-compatible AC performance, Pb-free SOIC-8 packaging, industrial temperature range (–40°C to +85°C), and dual-gate functional redundancy for signal conditioning in timing-critical backplane interfaces.
Technical Context
The SY100EL04ZG-TR implements two independent ECL-compatible AND/NAND gates in a single 8-pin SOIC package, with each gate sharing common VEE and VCC (GND) rails. Its differential ECL logic architecture enables rail-to-rail swing with fast edge rates and low skew between outputs.
It operates with VEE referenced negative supply (–4.2 V to –5.5 V) and VCC tied to GND, supporting true ECL-level signaling without level-shifting circuitry. Input pins D0/D1 feature internal 75 kΩ pull-downs, eliminating external biasing in unterminated or open-drain configurations.
Key Specifications

Pinout & Package
SY100EL04ZG-TR is housed in an 8-pin SOIC (Z8-1) package with 150 mil body width and NiPdAu Pb-free lead finish. Pin 1 is marked by a bar-line indicator per Micrel's Pb-free designation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (D0) | Data Input A | Primary input for Gate 1 AND/NAND function; internally pulled down to VEE via 75 kΩ |
| 3 (D1) | Data Input B | Secondary input for Gate 1 AND/NAND function; internally pulled down to VEE via 75 kΩ |
| 4 (NC) | No Connect | Internally unconnected; must be left floating or grounded |
| 5 (VCC) | Ground Reference | Tied to system GND; serves as return path for ECL output current |
| 6 (Q) | Output A | Complementary AND/NAND output of Gate 1; ECL-compatible swing referenced to VEE |
| 7 (VEE) | Negative Supply | –4.2 V to –5.5 V supply rail; powers internal logic and defines output voltage levels |
| 8 (Q) | Output B | Complementary AND/NAND output of Gate 2; electrically isolated but shares VEE/VCC with Pin 6 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent AND/NAND gates | Two fully functional ECL logic gates in one SOIC-8 package, reducing board space vs. discrete gate solutions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EL04DTG | Same 2-input AND/NAND function, identical SOIC-8 package, but uses Sn-Pb lead finish and commercial temp range (0°C to +70°C) | Limited to non-industrial environments; lacks Pb-free compliance and extended temperature qualification | Select when cost-sensitive commercial designs prioritize legacy supply chain over RoHS or thermal robustness |
| SN65ELT22DR | Single 2-input AND gate with LVDS-compatible outputs, 3.3 V supply, and 2.8 ns tPD - not ECL-compatible | Requires level translation for ECL systems; slower but lower power and CMOS-friendly | Choose only when migrating from ECL to LVDS infrastructure and redesigning supply/biasing networks |
Compared with MC100EL04DTG and SN65ELT22DR, the SY100EL04ZG-TR uniquely delivers Pb-free industrial-grade ECL performance in a drop-in SOIC-8 footprint-enabling legacy system upgrades without layout changes or signal integrity compromise.

FAQ
What is the supply voltage configuration for SY100EL04ZG-TR?
The SY100EL04ZG-TR requires a negative VEE supply between –4.2 V and –5.5 V, while VCC is connected to system ground (0 V). This dual-rail ECL configuration enables fast switching with controlled edge rates and is distinct from single-supply logic families. The SY100EL04ZG-TR does not operate with positive VCC voltages or CMOS-level supplies.
Does SY100EL04ZG-TR have internal input termination resistors?
Yes, SY100EL04ZG-TR integrates 75 kΩ pull-down resistors on both D0 and D1 inputs, referenced to VEE. These eliminate the need for external biasing components in unterminated or open-drain driving scenarios. This feature is confirmed in the device's official datasheet and applies specifically to the SY100EL04ZG-TR variant.
Is SY100EL04ZG-TR pin-compatible with SY10EL04ZG-TR?
Yes, SY100EL04ZG-TR and SY10EL04ZG-TR share identical pinout, package (Z8-1 SOIC), and electrical interface. The primary difference lies in VEE tolerance: SY100EL04ZG-TR supports –4.2 V to –5.5 V, whereas SY10EL04ZG-TR requires –4.75 V to –5.5 V. Both devices use the same pin assignments for D0, D1, Q, VCC, and VEE.
What is the maximum operating temperature for SY100EL04ZG-TR?
The SY100EL04ZG-TR is rated for industrial temperature operation from –40°C to +85°C. This specification is validated across all AC and DC parameters in the official Micrel datasheet and reflects guaranteed performance under sustained thermal stress-critical for deployment in base station radios and industrial controllers.
Can SY100EL04ZG-TR drive 50 Ω transmission lines directly?
SY100EL04ZG-TR outputs are designed for ECL-compatible termination, typically into 50 Ω to VEE. When properly terminated, it delivers clean 225 ps rise/fall times and maintains signal integrity up to ~2 GHz. Direct drive into unterminated 50 Ω lines is not recommended; proper source or end termination per ECL design rules is required for optimal SY100EL04ZG-TR performance.
