Product details
Overview
SY10EL05ZC-TR from Micrel is a 2-input differential ECL AND/NAND gate with 275 ps typical propagation delay, 225 ps typical output rise/fall time, and internal 75 kΩ input pull-down resistors. It operates from –5.2 V VEE (min) to –5.5 V (max) with VCC = GND, and is used in high-speed logic interfacing, clock distribution, and differential signal conditioning in telecom line cards.
For engineers reviewing the SY10EL05ZC-TR datasheet, SY10EL05ZC-TR pinout, SY10EL05ZC-TR application, or SY10EL05ZC-TR equivalent, key selection criteria include its ECL-compatible differential inputs/outputs, guaranteed AC performance across commercial temperature range (0°C to +70°C), and SOIC-8 (Z8-1) package compatibility with legacy ECL timing designs.
Technical Context
The SY10EL05ZC-TR implements true ECL differential logic using negative-voltage supply architecture (VEE = –5.2 V to –5.5 V, VCC = GND), enabling rail-to-rail swing and sub-nanosecond timing. Its differential inputs accept ≥150 mV peak-to-peak swing and feature clamp circuitry that pulls open inputs to HIGH via internal 75 kΩ resistors.
Functionally, it supports both AND/NAND and OR/NOR operations through input polarity inversion-differential OR/NOR is achieved by inverting both inputs before NAND logic. Output transitions are optimized for <350 ps (20%–80%) rise/fall times, supporting >1 GHz small-signal bandwidth in terminated 50 Ω systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 185–390 ps typ/max; enables synchronization in sub-1 ns logic paths |
| Output Rise/Fall Time (tr/tf) | 100–350 ps (20%–80%); supports clean edge integrity into 50 Ω loads | Input Swing (VPP) | ≥150 mV min; ensures reliable switching with low-amplitude differential signals |
| Supply Voltage (VEE) | –4.75 V to –5.5 V; requires negative ECL rail, not compatible with PECL or LVDS supplies |
| Power Supply Current (IEE) | 14–22 mA; fixed current draw independent of toggle rate, simplifying thermal design |
| Common Mode Range (VCMR) | –0.4 V max (referenced to high-side input); defines valid DC bias window for differential pair |
Pinout & Package

| 3 | VCC | Ground reference terminal (connected to system GND, not power rail) |
| 4 | Q (True Output) | Active-HIGH differential output; complements Q̅ on Pin 6 |
| 5 | VEE | Negative supply rail (–5.2 V to –5.5 V); primary current sink path |
| 6 | Q̅ (Complement Output) | Active-LOW differential output; provides full differential signaling pair with Pin 4 |
| 7, 8 | D0, D1 (Differential Inputs) | Second set of differential inputs-identical function to Pins 1 & 2; device contains two independent gates |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential ECL logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EL05DTG | Same pinout, identical AC specs, but ON Semiconductor part with Pb-free NiPdAu finish and industrial temp range (–40°C to +85°C) | Supports extended temperature operation; requires updated solder profile for Pb-free reflow | Select when industrial temp rating or RoHS compliance is mandatory |
| SN65ELT22DR | LVDS-input/LVDS-output dual gate; 3.3 V supply; 2.5 ns propagation delay; no internal pull-downs | Requires external biasing and level-shifting for ECL interface; lower speed but lower power | Select when migrating to LVDS infrastructure or reducing system power is prioritized over speed |
Compared with MC100EL05DTG, SY10EL05ZC-TR offers identical timing but commercial-temp-only operation and Sn-Pb finish; compared with SN65ELT22DR, it delivers >4× faster propagation at higher power and strict ECL voltage compliance-making it irreplaceable in legacy ECL timing chains.

FAQ
What is the operating supply voltage range for SY10EL05ZC-TR?
The SY10EL05ZC-TR requires a negative ECL supply: VEE must be between –4.75 V and –5.5 V, while VCC is connected to system ground (0 V). It does not operate with positive supplies or PECL-compatible voltages. This configuration ensures proper biasing of the internal differential pairs and guarantees the specified 275 ps typical propagation delay across the commercial temperature range.
Is SY10EL05ZC-TR pin-compatible with MC100EL05DTG?
Yes, SY10EL05ZC-TR is pin-compatible with MC100EL05DTG: both use the same 8-pin SOIC (Z8-1) footprint, identical pin functions (D0/D1, Q/Q̅, VCC, VEE), and match on AC and DC electrical specifications. However, MC100EL05DTG is rated for industrial temperature (–40°C to +85°C) and uses Pb-free NiPdAu plating, whereas SY10EL05ZC-TR is commercial-grade with Sn-Pb finish.
Can SY10EL05ZC-TR be used as an OR/NOR gate?
Yes, SY10EL05ZC-TR can implement differential OR/NOR logic: because a negative 2-input NAND is logically equivalent to a 2-input OR with inverted inputs, applying complementary signals to D0 and D1 transforms the NAND output into an OR function. The device's differential inputs and outputs preserve signal integrity throughout this functional reconfiguration without external components.
Does SY10EL05ZC-TR require external pull-down resistors on its inputs?
No, SY10EL05ZC-TR includes internal 75 kΩ pull-down resistors on all differential inputs, eliminating the need for external termination when inputs are unused or left floating. This feature ensures predictable HIGH logic state at the AND gate input under open conditions and simplifies PCB layout in sparse logic designs.
What is the minimum input signal swing required for guaranteed AC performance of SY10EL05ZC-TR?
The SY10EL05ZC-TR requires a minimum differential input swing of 150 mV peak-to-peak to guarantee full AC performance-including propagation delay, rise/fall time, and output amplitude-as specified in the datasheet. Below this threshold, timing parameters may degrade, though the device retains DC gain (~40) and will still switch with larger swings.
