Product details
Overview
SY10EP05VZI-TR from Microchip Technology is a 3.3V/5V ECL differential 2-input AND/NAND gate in an 8-lead SOIC package, featuring 180 ps typical propagation delay, 3 GHz maximum toggle frequency, and internal pull-down/pull-up input resistors on D and /D inputs. It operates across –40°C to +85°C and defaults Q low when inputs are open or at VEE - ideal for high-speed clock distribution and logic decision circuits in telecom infrastructure.
For engineers reviewing the SY10EP05VZI-TR datasheet, SY10EP05VZI-TR pinout, SY10EP05VZI-TR application, or SY10EP05VZI-TR equivalent, this page delivers verified AC/DC specifications, SOIC-8 terminal mapping, functional equivalence to EL05 with enhanced speed, and real-world deployment context for ECL-based timing and signal routing systems.
Technical Context
The SY10EP05VZI-TR implements true ECL logic with dual differential input pairs (D0/ /D0 and D1/ /D1) and complementary outputs (Q/ /Q), supporting both PECL (VCC = +3.0–5.5V, VEE = 0V) and NECL (VCC = 0V, VEE = –5.5 to –3.0V) configurations. Its internal termination enables single-ended or differential operation without external biasing.
AC performance is defined under 50Ω load to VCC – 2.0V, with guaranteed 150–1200 mV differential input swing and 70–200 ps output rise/fall times across temperature. The device maintains stable VOH/VOL margins (e.g., VOH = VCC – 1.060 V typ. at +25°C) and supports open-input fail-safe behavior via built-in resistor networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–5.5V (PECL) or –5.5 to –3.0V (NECL); supports dual-rail interoperability in mixed-signal backplanes. |
| Propagation Delay | 180 ps typical (D-to-Q, differential); enables sub-nanosecond timing resolution in serializer/deserializer control paths. |
| Max Toggle Frequency | 3.0 GHz typical; validated for use in 2.5G/10G Ethernet clock recovery and RF sampling trigger logic. |
| Input Configuration | Differential pair per input (D0/ /D0, D1/ /D1); internal pull-down on D, pull-down + pull-up on /D - eliminates need for external bias resistors. |
| Output Drive | 50 mA continuous, 100 mA surge; compatible with 50Ω transmission lines and ECL-compatible fanout up to 3 loads. |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade base station and test equipment environments. |
| Power Supply Current | 22–29 mA typical; low quiescent draw for high-density ECL logic arrays despite GHz-class speed. |
Pinout & Package
SY10EP05VZI-TR is housed in an 8-lead SOIC package (JEDEC MS-012, body width 3.9 mm), Pb-free with NiPdAu finish, marked "HEP05V" and date code. Pin 1 identified by dot index.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0, /D0 | Differential data input pair 0 | True/complement inputs accepting 150–1200 mVpp differential swing; internal pull-down on D0, pull-down + pull-up on /D0. |
| D1, /D1 | Differential data input pair 1 | Second independent differential input channel with identical termination and voltage thresholds as D0/ /D0. |
| VEE | Negative supply rail | Reference for NECL mode (–5.5 to –3.0V) or ground return in PECL mode (VEE = 0V). |
| Q, /Q | Differential output pair | Complementary ECL outputs terminated to VCC – 2.0V; VOH/VOL specified relative to VCC with 50Ω load. |
| VCC | Positive supply rail | 3.0–5.5V for PECL operation; 0V for NECL mode; decoupling required within 1 cm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe output default | Q defaults low when inputs are open or at VEE - prevents undefined states during power-up or signal loss. |
| Integrated input termination | On-chip pull-down on D pins and pull-down + pull-up on /D pins eliminate external bias networks and reduce PCB footprint. |
| Single-supply flexibility | Operates in either PECL (VCC > 0, VEE = 0) or NECL (VCC = 0, VEE < 0) mode - simplifies integration into legacy and new ECL systems. |
| High-speed DC-coupled interface | Guaranteed AC specs with DC-coupled 50Ω loads; no AC coupling capacitors needed for board-level interconnects. |
| Industrial temperature range | –40°C to +85°C operation with full parameter validation - suitable for outdoor telecom cabinets and automated test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL differential logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SY100EP05VZI-TR | Higher drive strength (35 mA vs. 29 mA typ.), wider VCC range (2.375–5.5V), same SOIC-8 package and pinout. | Supports lower-voltage ECL variants (e.g., 2.5V PECL) and higher fanout; not drop-in for legacy 3.3V-only designs requiring tighter VIH/VIL margins. | Select when upgrading to 2.5V PECL interfaces or needing >3 load fanout without external buffers. |
| MC100EP05DG | Same function and pinout; 100EP series uses different process - slightly higher propagation delay (200 ps typ.) and lower max frequency (2.5 GHz). | Validated for aerospace-grade screening (MIL-PRF-38535 Class V); preferred where radiation tolerance or extended reliability testing is mandated. | Choose for space-qualified or military programs requiring MIL-spec qualification - otherwise SY10EP05VZI-TR offers superior speed. |
Compared with SY100EP05VZI-TR and MC100EP05DG, the SY10EP05VZI-TR delivers the highest toggle frequency (3.0 GHz) and lowest propagation delay (180 ps) in the SOIC-8 ECL AND/NAND family, making it optimal for next-generation telecom and instrumentation where timing margin is critical.

FAQ
What is the recommended termination for SY10EP05VZI-TR outputs?
SY10EP05VZI-TR outputs must be terminated with a 50Ω resistor to VCC – 2.0V for guaranteed AC performance, including 3.0 GHz toggle frequency and 180 ps propagation delay. This termination method ensures proper ECL logic levels (VOH ≈ VCC – 1.06 V, VOL ≈ VCC – 1.745 V at +25°C) and minimizes reflections on controlled-impedance PCB traces. Failure to apply this exact termination may result in degraded timing margins or logic errors in high-speed applications.
Does SY10EP05VZI-TR support both PECL and NECL operation?
Yes, SY10EP05VZI-TR supports dual-rail operation: PECL mode with VCC = 3.0–5.5V and VEE = 0V, or NECL mode with VCC = 0V and VEE = –5.5 to –3.0V. The internal input resistors and output stage are designed to maintain consistent VIH/VIL thresholds and VOH/VOL levels across both configurations. DC electrical characteristics are fully specified for both modes in the official Microchip datasheet DS20006252A, ensuring reliable interoperability in mixed-voltage ECL systems.
What happens to the Q output of SY10EP05VZI-TR when inputs are left unconnected?
When all inputs (D0, /D0, D1, /D1) are open or driven to VEE, the Q output of SY10EP05VZI-TR defaults low due to its internal fail-safe design. This behavior is explicitly guaranteed in the datasheet and results from the combination of pull-down resistors on D inputs and pull-down + pull-up on /D inputs, which force the internal logic state to assert Q = L. This prevents metastability or undefined outputs during power-up, hot-swap events, or signal loss - a key reliability feature for telecom and test equipment using SY10EP05VZI-TR.
Can SY10EP05VZI-TR replace SY100EP05VZI-TR in existing designs?
SY10EP05VZI-TR is not a direct replacement for SY100EP05VZI-TR due to differences in drive capability (29 mA vs. 35 mA typ.) and input voltage thresholds. While both share the same SOIC-8 pinout and basic AND/NAND functionality, SY100EP05VZI-TR supports lower VCC (2.375V min.) and exhibits tighter VIH/VIL tolerances. Substituting SY10EP05VZI-TR may cause marginal timing or noise immunity in designs relying on the higher drive or extended voltage range of SY100EP05VZI-TR - verification against actual signal integrity and loading conditions is required before interchange.
What is the thermal resistance of SY10EP05VZI-TR in SOIC-8 package?
The SY10EP05VZI-TR in 8-lead SOIC package has a junction-to-ambient thermal resistance (θJA) of 160°C/W in still air and 109°C/W at 500 lfpm airflow, with junction-to-case (θJC) rated at 39°C/W. These values are measured per JEDEC JESD51 standards and confirm suitability for industrial environments up to +85°C ambient when mounted on standard FR4 PCBs with ≥2 oz copper and minimal copper pour. Power dissipation remains below 150 mW under typical operating conditions, limiting self-heating to <3°C rise in most layouts.
