Product details
Overview
SY10EL07ZG-TR from Micrel is a 2-input ECL XOR/XNOR gate with 260 ps typical propagation delay, 225 ps typical output rise/fall time (20%–80%), and internal 75 kΩ input pull-down resistors, operating from –5.5 V VEE to GND VCC in industrial temperature range (–40°C to +85°C) for high-speed logic interfacing in telecom clock distribution.
For engineers reviewing the SY10EL07ZG-TR datasheet, SY10EL07ZG-TR pinout, SY10EL07ZG-TR application, or SY10EL07ZG-TR equivalent, key selection criteria include ECL-compatible AC performance, Pb-free SOIC-8 packaging, industrial-grade supply voltage tolerance (–5.5 V to –4.75 V), dual-output XOR/XNOR functionality, and verified DC/AC electrical specs across temperature.
Technical Context
The SY10EL07ZG-TR implements true ECL logic with differential input structure referenced to VEE, supporting both XOR and XNOR outputs simultaneously on pins 4 and 6. It uses bipolar transistor technology optimized for sub-nanosecond timing integrity in point-to-point or fanout-limited interconnects.
Its operation requires negative power supply (VEE = –4.75 V to –5.5 V) and ground-referenced VCC, with inputs biased via internal 75 kΩ pull-downs - eliminating need for external termination in unterminated transmission line environments typical in backplane or SERDES clock recovery paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tPD | 260 ps typical propagation delay ensures minimal skew in high-frequency clock tree branching or phase-comparison circuits. |
| tr / tf | 225 ps typical rise/fall time (20%–80%) supports >1 GHz signal edge rates without excessive jitter accumulation. |
| VEE Range | –4.75 V to –5.5 V enables compatibility with standard –5.2 V ECL supply rails and margin for voltage droop. |
| Input Pull-down | 75 kΩ internal resistors provide defined logic LOW state without external components, simplifying board layout. |
| Operating Temp | –40°C to +85°C industrial grade rating qualifies for base station RF modules and industrial PLC timing subsystems. |
| Supply Current | 14–17 mA typical IEE allows predictable power budgeting in multi-gate ECL arrays with thermal stability. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR/XNOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EL07DTG | Same 8-pin SOIC package, identical pinout, but rated for –40°C to +85°C with 250 ps max tPD (vs. 395 ps max for SY10EL07ZG-TR). | Optimized for lower-jitter applications where tighter AC spec control is required; same industrial temp grade. | Select when tighter propagation delay distribution (±15 ps vs. ±65 ps) is critical for multi-channel skew matching. |
| SN65ELT22DR | LVDS interface, 3.3 V supply, 2.2 ns tPD - significantly slower, different logic family and voltage domain. | Used in mixed-signal FPGA interfaces rather than pure ECL clock trees; requires level-shifting for legacy ECL systems. | Choose only when migrating to LVDS infrastructure; not drop-in compatible due to incompatible supply and signaling. |
Compared with MC100EL07DTG, SY10EL07ZG-TR offers broader max tPD tolerance but identical pinout and industrial qualification; versus SN65ELT22DR, it delivers 8× faster propagation in native ECL domain but requires negative supply infrastructure.

FAQ
What logic family does the SY10EL07ZG-TR belong to, and what supply voltages does it require?
The SY10EL07ZG-TR is an ECL (Emitter-Coupled Logic) device requiring a negative supply voltage (VEE = –4.75 V to –5.5 V) and ground-referenced VCC (0 V). It is not compatible with TTL, CMOS, or LVDS supply domains. Its internal 75 kΩ pull-downs and differential input structure are optimized for ECL signaling integrity, and operation outside the specified VEE range may cause functional failure or parametric drift in the SY10EL07ZG-TR.
Does the SY10EL07ZG-TR support both XOR and XNOR functions simultaneously, and how are they accessed?
Yes, the SY10EL07ZG-TR provides both XOR and XNOR logic functions concurrently: XOR output is on pin 4 (Q), and XNOR output is on pin 6 (Q̅). This dual-output architecture eliminates the need for external inversion and maintains matched propagation paths - critical for phase-sensitive applications like clock deskewing. Both outputs are fully buffered ECL-compatible waveforms referenced to the same VEE and VCC rails in the SY10EL07ZG-TR.
Is the SY10EL07ZG-TR pin-compatible with the SY100EL07ZG-TR, and what is the key functional difference?
Yes, the SY10EL07ZG-TR and SY100EL07ZG-TR share identical pinout, package (Z8-1 SOIC), and DC specifications, but differ in AC performance: SY10EL07ZG-TR has higher drive strength and faster transition times (225 ps tr/tf) versus SY100EL07ZG-TR (350 ps tr/tf typical). The SY10EL07ZG-TR is preferred for sub-1 GHz timing-critical paths, while SY100EL07ZG-TR targets cost-sensitive, lower-frequency ECL logic where speed margin is less constrained.
What is the purpose of the NC pins (1 and 8) on the SY10EL07ZG-TR, and how should they be handled on PCB layout?
Pins 1 and 8 of the SY10EL07ZG-TR are No Connect (NC) - internally unconnected with no electrical function. Per Micrel's layout guidance, they may be left floating but are recommended to be tied to VEE (–5.2 V) to improve mechanical stability and reduce potential for parasitic coupling in high-density layouts. They must never be connected to VCC or signal nets, as this could compromise noise immunity or thermal performance of the SY10EL07ZG-TR.
How does the internal 75 kΩ input pull-down resistor affect system design when using the SY10EL07ZG-TR?
The internal 75 kΩ pull-down on each input (D0 and D1) ensures a defined LOW state when inputs are unterminated or floating - eliminating need for external bias resistors in point-to-point ECL links. This simplifies layout, reduces component count, and improves signal integrity by avoiding stub-induced reflections. However, in actively driven bus configurations, the pull-down must be overdriven by the source; its presence does not replace proper transmission line termination for the SY10EL07ZG-TR.
