Product details
Overview
MC10H189PG from ON Semiconductor is a hex inverter with common enable input operating in MECL 10H logic family, delivering 1.3 ns typical propagation delay, −5.2 V VEE supply operation, and −1.02 V to −0.735 V VOH across 0°C to +75°C. It functions as a high-speed level-shifting inverter bank in ECL-based clock distribution and data path conditioning circuits.
For engineers reviewing the MC10H189PG datasheet, pinout, applications, or equivalent options, this part supports precise timing-critical enable-controlled inversion in telecom line cards, test equipment front-ends, and high-speed digital instrumentation where MECL 10K compatibility and sub-2 ns delay are required.
Technical Context
The MC10H189PG implements six independent inverting gates sharing a single active-low Enable input (pin 1), with all outputs forced low when Enable is high. Its internal voltage-compensated design maintains stable noise margin (150 mV) across temperature and supply variation.
Each inverter stage uses emitter-coupled logic with differential pair topology, terminated into −2.0 V via 50 Ω, supporting DC-coupled interconnects. The device requires dual supplies: VCC1 (pin 1) and VCC2 (pin 16) at ground, and VEE (pin 8) at −5.2 V ±5%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 0.7–2.3 ns (Enable-to-output and data-to-output); enables <2 ns setup/hold timing in synchronous bus interfaces. |
| Supply Voltage (VEE) | −5.2 V ±5%; defines logic threshold and output swing for interoperability with MECL 10K/10H systems. |
| VOH / VOL | −1.02 V to −0.735 V / −1.95 V to −1.60 V; ensures >150 mV noise margin under full temp range and load. |
| Power Dissipation | 180 mW typical per package (no load); compatible with dense PCB layouts without forced airflow. |
| Operating Temperature | 0°C to +75°C; validated for industrial-grade telecom and instrumentation environments. |
| Input Current (IinL) | 0.5 µA min at low input; reduces loading on preceding driver stages in cascaded ECL fanout chains. |
Pinout & Package
MC10H189PG is supplied in a 16-pin plastic dual-in-line package (PDIP), case 648, with Pb-free finish (G suffix). Pin 1 = VCC1, Pin 8 = VEE, Pin 16 = VCC2 - all VCC pins tied to ground in standard MECL 10H configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC1 | Ground reference for first three inverters; must be connected to system ground. |
| 2–4, 5–7 | AIN–CIN, DIN–FIN | Six independent inverter inputs; accept MECL-compatible negative-voltage logic levels. |
| 8 | VEE | Main negative supply (−5.2 V); sets logic thresholds and output swing amplitude. |
| 9–11, 12–14 | AOUT–COUT, DOUT–FOUT | Six complementary inverted outputs; each sourced from open-emitter output stage. |
| 15 | Enable | Active-low global enable; forces all six outputs low when high (non-inverting control). |
| 16 | VCC2 | Ground reference for last three inverters; must be connected to system ground. |
Key Features
| Feature | Design Value |
|---|---|
| MECL 10K pinout and functional compatibility | Direct drop-in replacement for MC10K189 in existing designs without layout change. |
| 100% propagation delay improvement vs. 10K | Reduces critical path delay in high-speed state machines and serializer/deserializer clock trees. |
| Voltage-compensated internal biasing | Maintains consistent switching thresholds across −5.2 V supply tolerance and temperature drift. |
| 150 mV guaranteed noise margin | Enables robust operation in electrically noisy backplane or mixed-signal board environments. |
| Pb-free PDIP packaging (G suffix) | Complies with RoHS Directive 2011/65/EU without derating or performance compromise. |
Applications
| Digital Test Equipment | Telecom Line Card Timing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter with enable applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100H189P | Higher speed grade (100H series): 0.6 ns typical tpd; requires −5.2 V VEE but tighter VIH/VIL tolerances. | Used in military/aerospace systems requiring extended temperature range (−55°C to +125°C). | Select when sub-1 ns delay and extended temp operation are mandatory; not drop-in due to tighter input specs. |
| SN74AS863N | TTL-compatible, 5 V single-supply operation; 3.5 ns tpd; no enable function - requires external gating logic. | Deployed in legacy industrial controllers using 5 V TTL logic families. | Choose only if redesigning for TTL infrastructure; incompatible voltage domain and lacks integrated enable. |
Compared with MC10H189PG, MC100H189P offers faster timing at higher cost and stricter supply stability requirements, while SN74AS863N provides TTL-level integration at the expense of speed, power efficiency, and enable functionality - making MC10H189PG optimal for MECL-based high-speed systems needing compact enable control.

FAQ
What is the recommended termination for MC10H189PG outputs?
MC10H189PG outputs must be terminated with a 50 Ω resistor to −2.0 V to meet AC specifications including propagation delay and rise/fall times. This termination matches standard ECL transmission line practice and ensures signal integrity in point-to-point or short-bus configurations. Failure to apply correct termination will cause timing violations and increased jitter in the MC10H189PG output waveform.
Can MC10H189PG operate with VCC pins left floating?
No - MC10H189PG requires VCC1 (pin 1) and VCC2 (pin 16) to be connected to system ground. These pins serve as current return paths for internal emitter followers and are not optional. Leaving them unconnected will result in undefined output states and potential device damage. The MC10H189PG datasheet explicitly specifies grounding both VCC pins for proper operation.
Does MC10H189PG support hot-swap or live-insertion?
No - MC10H189PG is not rated for hot-swap operation. Its absolute maximum ratings assume powered-up sequencing with VEE applied before any input signals, and it lacks built-in current limiting or ESD protection beyond standard HBM levels. Applying inputs before VEE stabilization may cause latch-up or parametric shift. System-level hot-swap capability must be implemented externally when using MC10H189PG.
Is MC10H189PG pin-compatible with MC10K189?
Yes - MC10H189PG is a functional and pinout duplication of the MC10K189, as confirmed in the official ON Semiconductor datasheet. Both share identical pin assignments, logic behavior, and DC electrical characteristics, allowing direct replacement without PCB modification. However, MC10H189PG delivers improved propagation delay and noise margin while maintaining full 10K interoperability.
What is the maximum allowable VEE slew rate for MC10H189PG?
The MC10H189PG datasheet does not specify a maximum VEE slew rate. However, thermal equilibrium requirements indicate that VEE must stabilize within the operating range (−8.0 V to 0 V) before applying input signals. Rapid VEE transients exceeding 1 V/µs may induce transient output glitches or temporary loss of noise margin. For reliable startup, ramp VEE monotonically to −5.2 V over ≥100 µs prior to enabling the MC10H189PG.
