Product details

Overview

MC10111P from ON Semiconductor is a dual 3-input/3-output ECL NOR gate IC designed for high-speed clock distribution and logic-level gating in systems requiring minimal skew across parallel outputs. It delivers 2.4 ns typical propagation delay (all outputs loaded), 2.2 ns typical rise/fall time (20%–80%), and supports simultaneous driving of three 50 Ω transmission lines terminated to −2.0 V. Its triple V_CC pins (pins 1, 15, 16) enable independent power routing for noise isolation in critical timing paths.

For engineers reviewing the MC10111P datasheet, pinout, applications, or equivalent options, this device is selected for ultra-low-skew clock fanout, wired-OR logic reduction, and ECL-compatible signal conditioning where sub-3 ns timing and deterministic output matching are required.

Technical Context

The MC10111P implements two independent ECL NOR gates, each with three inputs and three buffered outputs sharing identical electrical characteristics. All outputs switch between −0.810 V (logic 1, +25°C) and −1.850 V (logic 0, +25°C) under 50 Ω load to −2.0 V, with guaranteed VOH/VOL margins across −30°C to +85°C.

Its architecture supports wire-ORing via open-collector–like behavior using emitter-follower outputs - no external pull-up resistors needed - and requires separate V_CC connections per gate group (V_CC1 for Gate A, V_CC2 for Gate B) to minimize inter-gate crosstalk and supply-induced skew.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation Delay	2.4 ns typ (all outputs loaded with 50 Ω to −2.0 V); ensures synchronized edge delivery across all six outputs.
Rise/Fall Time	2.2 ns typ (20%–80%); enables clean transitions into high-speed transmission lines without excessive ringing.
Output Voltage Logic 1	−0.810 V min at +25°C; compatible with standard MECL 10K input thresholds (VIHmax = −0.810 V).
Output Voltage Logic 0	−1.850 V max at +25°C; provides sufficient noise margin against V_EE = −5.2 V rail.
Power Dissipation	80 mW typ per gate (no load); allows thermal management in dense ECL logic arrays without forced cooling.
Input Current (High)	425 μA max at +25°C; defines termination resistor sizing for driven inputs in cascaded ECL stages.
Supply Pins	Three V_CC pins (1, 15, 16); permits localized decoupling and reduces ground bounce between gate sections.

Pinout & Package

MC10111P is housed in a 16-pin plastic dual-in-line package (PDIP-16, Case 648), with 0.300-inch wide body and 0.100-inch lead pitch. Pin 1 is top-left corner (notch-up orientation), and pin 8 is V_EE (−5.2 V common emitter reference).

Pin/Terminal	Circuit Role	Design Meaning
1, 15	V_CC1	Positive supply for Gate A (inputs AIN, outputs AOUT); must be decoupled locally to suppress switching noise.
16	V_CC2	Positive supply for Gate B (inputs BIN, outputs BOUT); electrically isolated from V_CC1 to prevent inter-gate coupling.
8	V_EE	Common emitter reference (−5.2 V); serves as return path for all inputs and outputs; requires low-inductance grounding.
5, 6, 7	AIN1–AIN3	Three active-low inputs for Gate A; logic high = −0.810 V, logic low = −1.850 V; VIHmax = −0.810 V.
2, 3, 4	AOUT1–AOUT3	Three emitter-follower outputs of Gate A; identical timing and voltage levels; support wired-OR connection.
11, 12, 13	BIN1–BIN3	Three active-low inputs for Gate B; electrically identical to AIN pins but referenced to V_CC2.
10, 9, 14	BOUT1–BOUT3	Three emitter-follower outputs of Gate B; fully independent timing domain from AOUT pins.

Key Features

Feature	Design Value
Dual independent NOR gates with 3-input/3-output topology	Reduces gate count by 3× vs. single-output equivalents; enables compact logic synthesis in clock trees.
Matched propagation delay across all six outputs	Ensures ≤0.2 ns skew between AOUTx and BOUTx outputs under identical loading - critical for phase-aligned clock fanout.
Triple V_CC pin assignment (pins 1, 15, 16)	Allows separate power routing and decoupling for each gate section, minimizing supply-induced jitter.
Wired-OR capability without external components	Emitter-follower outputs sink current only; multiple outputs can be tied together to implement OR logic without level-shifting.
Guaranteed operation from −30°C to +85°C	Supports industrial and telecom infrastructure applications where ambient temperature extremes affect timing stability.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC100116FN	Single 3-input/3-output NOR in PLCC-20; same electrical specs but different package and pinout.	Requires PCB redesign due to surface-mount PLCC footprint and non-DIP pin mapping.	Select when board space constraints favor SMT or when PLCC-based legacy designs require drop-in functional replacement.
SN10111L	Ceramic DIP-16 variant with identical logic and timing; higher reliability, hermetic sealing, and extended temperature range (−55°C to +125°C).	Suitable for military/aerospace deployments where moisture resistance and thermal cycling endurance are mandatory.	Choose for mission-critical systems requiring MIL-PRF-38535 compliance and long-term reliability beyond commercial grade.

Compared with MC10111P, MC100116FN offers identical functionality in a surface-mount package but demands layout changes, while SN10111L provides enhanced environmental ruggedness and extended temperature operation at higher cost and longer lead time.

FAQ

What is the recommended termination for MC10111P outputs?

Each MC10111P output must be terminated with a 50 Ω resistor to −2.0 V to meet specified timing (tpd = 2.4 ns typ) and waveform integrity (tr/tf = 2.2 ns typ). This matches the characteristic impedance of standard high-speed transmission lines and prevents reflections that degrade edge fidelity. The −2.0 V termination reference is distinct from V_EE (−5.2 V) and must be generated separately using a precision voltage source or resistor divider.

Can MC10111P drive TTL or CMOS inputs directly?

No, MC10111P cannot drive TTL or CMOS inputs directly due to incompatible voltage levels: its outputs swing between −0.81 V (logic 1) and −1.85 V (logic 0), while TTL/CMOS require positive logic rails (0 V/5 V or 0 V/3.3 V). Level translation via ECL-to-TTL translators (e.g., MC10124) or resistor-based bias networks is required to interface MC10111P with non-ECL logic families.

Why does MC10111P have three VCC pins instead of one?

The MC10111P uses three V_CC pins (pins 1, 15, 16) to isolate power delivery for Gate A (V_CC1 on pins 1 and 15) and Gate B (V_CC2 on pin 16). This separation prevents switching noise from one gate's outputs from modulating the other gate's supply rail - a key requirement for maintaining sub-3 ns timing accuracy and minimizing inter-gate skew in sensitive clock distribution applications.

Is MC10111P pin-compatible with MC10111L or MC10111FN?

No, MC10111P is not pin-compatible with MC10111L (CDIP-16) or MC10111FN (PLCC-20): although all share identical logic function and DC/AC specifications, their physical packages differ in lead count, pitch, and pin numbering. MC10111P (PDIP-16) and MC10111L (CDIP-16) share the same 16-pin DIP footprint but differ in material (plastic vs. ceramic) and thermal performance; MC10111FN requires a 20-pin PLCC socket and full PCB redesign.

What is the maximum operating frequency supported by MC10111P?

The MC10111P does not specify a maximum clock frequency in its datasheet because it is a combinational logic device, not a sequential element. Its usable frequency limit is determined by propagation delay (2.4 ns typ) and system-level factors including trace length, termination quality, and input slew rate. In practice, MC10111P reliably supports data rates up to 350 Mbps (3.5 ns period) in well-designed ECL systems with controlled impedance routing and proper termination.
