Product details
Overview
SY10EP01VKC-TR from Micrel is a 4-input ECL OR/NOR gate operating at 3.3V or 5V supply, delivering 230ps typical propagation delay, 3GHz maximum toggle frequency, and differential Q and /Q outputs with internal 75kΩ input pulldowns. It is used in high-speed clock distribution and logic decision circuits in telecom line cards and test equipment.
For engineers reviewing the SY10EP01VKC-TR datasheet, SY10EP01VKC-TR pinout, SY10EP01VKC-TR application, or SY10EP01VKC-TR equivalent, this page provides verified functional identity, validated DC/AC electrical specs, confirmed MSOP-8 package mapping, truth table behavior under open-input conditions, and two documented alternative parts for ECL logic replacement scenarios.
Technical Context
The SY10EP01VKC-TR implements true ECL logic with dual complementary outputs (Q and /Q), supporting both positive- and negative-VCC configurations (VCC = 0V/VEE = –5.5V or VCC = +3.3V to +5.5V/VEE = 0V). Its inputs are internally pulled down to VEE via 75kΩ resistors, ensuring Q defaults LOW when all D0–D3 are open.
It meets ECL Pro™ timing standards with 200ps typical tPD across temperature, 110ps typical rise/fall times, and <20ps device skew. All AC parameters are specified under 50Ω termination to VCC – 2.0V, consistent with standard ECL load conditions.

Key Features
| Feature | Design Value |
|---|---|
| Single-gate OR/NOR duality | One device delivers both OR and NOR logic functions via Q and /Q outputs - eliminates need for discrete inversion |
| Open-input fail-safe | 75kΩ internal pulldowns guarantee Q = LOW when all D0–D3 float - prevents metastability in unconnected logic paths |

Use Value: Matched Q and /Q rise/fall times (<110ps typ) preserve phase coherence between parallel processing paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL OR/NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC10EP01DTG | Same 4-input OR/NOR function, 200ps tPD, but in 8-pin TSSOP; VEE range limited to –3.0V to –5.5V only (no positive-rail mode) | Lacks dual-supply flexibility; requires dedicated negative rail design | Select when legacy TSSOP footprint compatibility is required and system uses fixed negative supply |
| SN65ELT22D | 2-input OR/NOR with 1.2ns tPD; LVDS-compatible outputs, not ECL; no internal pulldowns | Slower, different signaling standard, requires external biasing for open-input stability | Select only if migrating to LVDS infrastructure and can accept higher latency and added external components |
Compared with MC10EP01DTG and SN65ELT22D, SY10EP01VKC-TR uniquely supports both positive- and negative-rail ECL operation while guaranteeing 3GHz toggle capability and fail-safe open-input behavior - critical for reconfigurable telecom timing systems.

FAQ
What logic family and voltage modes does SY10EP01VKC-TR support?
SY10EP01VKC-TR is an ECL-family device supporting two distinct supply configurations: negative-rail mode (VCC = 0V, VEE = –5.5V to –3.0V) and positive-rail mode (VCC = +3.3V to +5.5V, VEE = 0V). It is not compatible with TTL, CMOS, or LVDS signaling levels. The SY10EP01VKC-TR maintains identical AC/DC performance across both modes, including 200ps typical propagation delay and 3GHz toggle frequency.
Does SY10EP01VKC-TR require external pull-down resistors on its inputs?
No, SY10EP01VKC-TR includes internal 75kΩ pulldown resistors on all four inputs (D0–D3) referenced to VEE. This ensures Q defaults LOW when inputs are left unconnected - a key reliability feature for hot-swap or partial-configuration scenarios. External pull-downs are unnecessary and may degrade noise margin or increase power draw. The SY10EP01VKC-TR datasheet explicitly confirms this behavior in the Features and Truth Table sections.
What is the guaranteed maximum propagation delay for SY10EP01VKC-TR across temperature?
The SY10EP01VKC-TR guarantees a maximum propagation delay (tPD) of 300ps over the full operating temperature range (–40°C to +85°C), with 200ps typical at +25°C. This specification applies to the D→Q path under standard 50Ω load conditions (terminated to VCC – 2.0V). The SY10EP01VKC-TR maintains tight skew (<20ps) between all input-to-output paths, ensuring deterministic timing in parallel logic trees.
Can SY10EP01VKC-TR be used as a drop-in replacement for EL01 or E101 devices?
Yes, SY10EP01VKC-TR is functionally equivalent to the EL01 and E101 (quad version) devices per Micrel's official documentation, sharing identical logic function, pinout, timing, and DC characteristics. However, SY10EP01VKC-TR uses MSOP-8 packaging (K8-1), whereas EL01 typically uses SOIC-8 (Z8-1); mechanical compatibility requires footprint verification. The SY10EP01VKC-TR retains full electrical interoperability in both negative- and positive-rail ECL systems.
What termination is required for SY10EP01VKC-TR outputs to meet AC specifications?
SY10EP01VKC-TR outputs must be terminated to VCC – 2.0V using a 50Ω resistor to meet guaranteed AC performance (tPD, tr/tf, fMAX). This matches standard ECL termination practice. For VCC = 0V/VEE = –5.5V operation, termination is to –2.0V; for VCC = +3.3V operation, termination is to +1.3V. The SY10EP01VKC-TR datasheet specifies all AC parameters under this exact condition - deviation invalidates timing guarantees.
