Product details
Overview
SY10EL05ZI from Micrel is an industrial-grade 2-input differential AND/NAND gate IC operating with –5.5V VEE and GND VCC, delivering 275ps typical propagation delay, 225ps typical output rise/fall time, and 150mV minimum input swing. It functions as a high-speed logic gate in ECL-compatible timing and data-path circuits, such as clock distribution networks and high-frequency comparators.
For engineers reviewing the SY10EL05ZI datasheet, SY10EL05ZI pinout, SY10EL05ZI application, or SY10EL05ZI equivalent, key selection criteria include its differential ECL interface, industrial temperature range (–40°C to +85°C), SOIC-8 package with Sn-Pb finish, and guaranteed AC performance under VEE = –5.2V conditions.
Technical Context
The SY10EL05ZI implements true differential ECL logic with internal 75kΩ pull-down resistors on inputs, enabling robust open-input handling where unconnected D0/D1 default HIGH. Its output stage drives complementary Q and Q̅ signals with matched 100–350ps rise/fall times across temperature.
It operates with VEE referenced negative supply (–4.75V to –5.5V) and VCC at GND, requiring termination to –2V for proper ECL biasing. The device supports both AND/NAND functionality and-via input inversion-OR/NOR operation, leveraging differential signaling for noise immunity in high-speed backplanes and test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 275ps typical - ensures sub-400ps logic decision latency in critical timing paths |
| Output Rise/Fall Time (tr/tf) | 225ps typical - enables >2GHz signal transitions with controlled edge integrity |
| Minimum Input Swing (VPP) | 150mV - defines smallest differential voltage needed to guarantee full AC performance |
| Common Mode Range (VCMR) | –0.4V min - sets lower bound of valid input common-mode voltage relative to VEE+3.0V |
| Supply Voltage (VEE) | –5.2V typical - requires negative rail regulation and proper ECL termination network |
| Power Supply Current (IEE) | 18mA typical - determines total power draw per gate at VEE = –5.2V |
Pinout & Package
SY10EL05ZI is housed in an 8-pin SOIC package (Z8-1, .150" wide) with Sn-Pb lead finish, rated for industrial temperature operation (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | D0, D1 (Differential Inputs) | True differential pair accepting ECL-level signals; internally pulled down to VEE via 75kΩ resistors |
| 3 | VCC | Connected to GND; serves as reference for output emitter-follower stage |
| 4 | Q (True Output) | Active-low ECL output; complements Q̅, requires –2V termination for standard logic levels |
| 5 | VEE | Negative supply rail (–4.75V to –5.5V); establishes bias point for all internal transistors |
| 6 | Q̅ (Complement Output) | Active-high ECL output; provides inverted logic level for differential bus driving |
| 7, 8 | D0, D1 (Differential Inputs) | Second set of differential inputs - identical function to pins 1 and 2; enables dual-gate layout sharing |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential ECL gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SY100EL05ZI | Higher IEE (21mA typ), wider VEE range (–4.2V to –5.5V), same AC specs | Optimized for lower-voltage ECL systems; less sensitive to VEE droop | Select when operating near –4.5V VEE or requiring tighter current regulation |
| MC10EL05DT | Same pinout, identical AC performance, but uses different internal bias architecture | Drop-in replacement in most Micrel-designed boards; validated in Motorola reference designs | Choose for second-source assurance where MC10EL05DT is already qualified |
Compared with SY10EL05ZI, SY100EL05ZI offers improved low-voltage margin while MC10EL05DT provides cross-manufacturer design continuity-both retain the same 275ps tPD and SOIC-8 footprint but differ in supply sensitivity and qualification history.

FAQ
What is the operating temperature range for SY10EL05ZI?
The SY10EL05ZI is rated for industrial operation from –40°C to +85°C. This range is confirmed in the "PACKAGE/ORDERING INFORMATION" table where SY10EL05ZI is explicitly assigned to the Industrial temperature grade. All AC and DC electrical characteristics in the datasheet are specified across this full range, including the 275ps typical propagation delay and 225ps typical output transition times.
Does SY10EL05ZI require external pull-down resistors on its inputs?
No, SY10EL05ZI does not require external pull-down resistors. The datasheet states it includes "Internal 75KΩ input pull-down resistors" on all differential inputs (D0, D1). This feature ensures a defined HIGH logic state when inputs are left open, eliminating the need for discrete bias components and simplifying PCB layout in sparse or modular designs.
What is the correct termination scheme for SY10EL05ZI outputs?
SY10EL05ZI outputs (Q and Q̅) must be terminated to –2V using 50Ω resistors to match standard ECL logic levels. This is derived from the common-mode range specification (VCMR) and typical application circuits in Micrel documentation. Termination to –2V ensures proper logic thresholds and maintains signal integrity at 225ps edge rates, especially over controlled-impedance traces.
Is SY10EL05ZI pin-compatible with SY100EL05ZI?
Yes, SY10EL05ZI and SY100EL05ZI share identical pinout, package (Z8-1 SOIC), and terminal functions. Both use pins 1/2 and 7/8 for D0/D1 inputs, pin 4 for Q, pin 6 for Q̅, pin 3 for VCC (GND), and pin 5 for VEE. However, their VEE operating ranges differ: SY10EL05ZI requires –4.75V to –5.5V, while SY100EL05ZI supports –4.20V to –5.5V.
Can SY10EL05ZI be used as an OR/NOR gate?
Yes, SY10EL05ZI can implement OR/NOR functionality by inverting both differential inputs. As stated in the datasheet: "a negative 2-input NAND is equivalent to a 2-input OR function with inverted inputs." Since the device has fully differential inputs and outputs, applying complementary signals to D0/D1 allows it to serve as a differential OR/NOR gate without external inversion logic.
