Product details

Overview

MC10189P from ON Semiconductor is a high-speed ECL hex inverter with common enable, operating across –30°C to +85°C, featuring 2.0 ns propagation delay (Y→Q), –1.06 V logic-1 output voltage, and 200 mW typical package power dissipation. It functions as a level-sensitive logic gate array in high-frequency timing and data path control circuits.

For engineers reviewing the MC10189P datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, PDIP-16 package mapping, truth table behavior, enable-controlled output states, and validated alternative parts for ECL logic replacement scenarios.

Technical Context

The MC10189P implements six independent inverting gates sharing a single active-low Enable input (pin 9); all outputs go low when Enable is high. Each gate follows standard MECL 10,000-series differential switching with V_EE = –5.2 V, V_CC1 = pin 1, V_CC2 = pin 16.

Logic thresholds are defined by VOHA (–1.08 V min) and VOLA (–1.655 V max) at –30°C, with outputs terminated into 50 Ω to –2.0 V. Propagation delays are asymmetric: t_PHL = 1.1 ns, t_PLH = 3.9 ns under load, confirming its use in edge-triggered or pulse-width-critical paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation Delay (Y→Q)	2.0 ns - determines maximum toggle frequency in synchronous logic chains
Output Voltage (Logic 1)	–1.060 V at –30°C - sets compatible receiver threshold margin in ECL systems
Output Voltage (Logic 0)	–1.890 V at –30°C - defines noise floor and differential swing (0.83 V) for signal integrity
Enable Input Threshold	V_IL ≤ –1.890 V, V_IH ≥ –0.890 V - ensures clean enable assertion across temperature
Power Dissipation	200 mW typical (no load) - informs thermal design for dense PCB layouts
Operating Temperature	–30°C to +85°C - qualifies for industrial-grade timing and control applications

Pinout & Package

MC10189P is supplied in a 16-pin plastic dual-in-line package (PDIP-16, Case 648), with 0.300-inch body width and 0.100-inch lead pitch. Pin 1 is V_CC1, pin 16 is V_CC2, and pin 8 is V_EE. All inputs and outputs are ECL-compatible single-ended terminals.

Pin/Terminal	Circuit Role	Design Meaning
1	V_CC1	Positive supply for A/B/C sections; must be decoupled locally
2–4, 10–12	AOUT–COUT, FOUT–DOUT	Inverted outputs; each drives 50 Ω to –2.0 V reference
5–7, 13–15	AIN–CIN, FIN–DIN	Input terminals; referenced to V_EE, require proper termination
8	V_EE	Common emitter supply (–5.2 V); ground reference for all logic levels
9	Enable (active low)	Global gate enable; high = all outputs forced low (tri-state equivalent)
16	V_CC2	Positive supply for D/E/F sections; separate from V_CC1 for noise isolation

Key Features

Feature	Design Value
Hex inverting function with shared enable	Reduces component count in bus inversion or clock gating where synchronized disable is required
2.0 ns Y→Q propagation delay	Supports >250 MHz toggle rates in critical data path buffering
MECL 10,000 series compatibility	Ensures interoperability with MC10114, MC10115, and other legacy ECL families
–30°C to +85°C operation	Validates use in non-temperature-controlled industrial control cabinets and telecom line cards
Separate V_CC1/V_CC2 supplies	Enables partitioned power routing to minimize crosstalk between logic sections

Equivalent & Alternatives

The following parts are listed as comparable options for similar ECL hex inverter with enable applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC100189P	Higher speed: t_pd = 1.5 ns (Y→Q); requires V_EE = –4.5 V, not –5.2 V	Used in newer designs targeting <1.6 ns jitter budgets; incompatible with legacy –5.2 V rails	Select MC100189P only if redesigning power delivery and verifying receiver compatibility
SN74AS868N	TTL-compatible, 5 V supply; 4.5 ns delay; no enable input; different logic family	Suitable for cost-sensitive, lower-speed industrial controllers where ECL performance is unnecessary	Choose SN74AS868N when interfacing with 5 V TTL/CMOS systems and thermal/power constraints preclude ECL

Compared with MC10189P, MC100189P offers faster switching but mandates revised biasing, while SN74AS868N trades speed and enable functionality for broader voltage compatibility and lower system cost-neither is pin-compatible, requiring layout changes.

FAQ

What logic family does the MC10189P belong to, and what supply voltages does it require?

The MC10189P is a member of the MECL 10,000 series ECL logic family. It requires three supply connections: V_CC1 (pin 1), V_CC2 (pin 16), and V_EE (pin 8) at –5.2 V. The device operates with differential logic levels referenced to V_EE, and outputs are specified for 50 Ω termination to –2.0 V. This configuration is essential for correct MC10189P functionality and signal integrity.

How does the Enable input function on the MC10189P, and what happens to outputs when it is asserted?

The Enable input (pin 9) is active low: when pulled low, all six inverters operate normally; when high, all outputs are forced low regardless of input states. This behavior provides synchronous disable capability without external gating logic. For MC10189P, this feature enables safe power-down sequencing and fault-mitigation in real-time control systems.

Is the MC10189P pin-compatible with other packages in the same family, such as the PLCC version?

No, the MC10189P (PDIP-16) is not pin-compatible with the MC10189FN (PLCC-20). The PLCC variant has 20 pins and different pin assignments, including dedicated ground and additional supply pins. Direct substitution requires PCB redesign. Always verify pin mapping using the ON Semiconductor MECL Data Book (DL122/D) before replacing MC10189P with any alternate package.

What is the guaranteed propagation delay specification for MC10189P across temperature?

The MC10189P guarantees t_pd = 2.0 ns (Y→Q) at –30°C and +25°C, and 2.5 ns (X→Q) under the same conditions. At +85°C, the datasheet specifies t_PLH ≤ 3.9 ns and t_PHL ≤ 1.1 ns. These values are measured with 50 Ω loads to –2.0 V and define the worst-case timing window for MC10189P in high-frequency designs.

Can the MC10189P be used in new designs, and what lifecycle considerations apply?

Yes, the MC10189P remains available through authorized distributors and Aetrix Electronics with ongoing production support. While it is a mature part, ON Semiconductor maintains controlled-lifecycle status for the MECL 10,000 series. Customers designing with MC10189P benefit from documented long-term availability planning, obsolescence notifications, and full traceability-critical for industrial and telecom infrastructure programs.
