onsemi MC10H210P

Overview

MC10H210P from ON Semiconductor is a dual 3-input/3-output MECL 10K-compatible OR gate in a 16-pin PDIP package, delivering 1.0 ns typical propagation delay, −1.95 V to −0.735 V output voltage swing, and 160 mW typical power dissipation. It drives up to six transmission lines simultaneously and supports wire-ORing of multiple logic levels for clock distribution with minimized skew.

For engineers reviewing the MC10H210P datasheet, pinout, applications, or equivalent options, this device is selected for high-speed ECL logic systems requiring precise timing alignment, low-noise clock fanout, and deterministic multi-output gating in telecom backplanes and test instrumentation.

Technical Context

The MC10H210P implements two independent 3-input OR gates, each with three complementary outputs (AOUT/AOUT/AOUT and BOUT/BOUT/BOUT), enabling parallel signal distribution without external buffering. Its voltage-compensated design maintains stable switching thresholds across −5.2 V VEE supply and 0 °C to +75 °C operating temperature.

Each gate operates with MECL 10K logic levels: VIH = −1.17 V min, VIL = −1.95 V max, VOH = −0.84 V min, VOL = −1.95 V max at 25 °C. Outputs are internally terminated for 50 Ω to −2.0 V, supporting direct connection to transmission lines without external resistors.

Key Specifications

Pinout & Package

MC10H210P uses 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 when notch faces up; VEE is at pin 8 (common ground reference), VCC1 at pins 1 & 15, VCC2 at pin 16.

FAQ

What is the recommended termination for MC10H210P outputs?

MC10H210P outputs must be terminated with a 50 Ω resistor to −2.0 V, as specified in the datasheet's AC parameter test conditions. This termination ensures proper signal integrity, minimizes reflections on transmission lines, and guarantees the published propagation delay and voltage swing values. Using any other termination scheme will invalidate the rated 1.0 ns typical tpd and may cause timing violations in high-speed systems using MC10H210P.

Does MC10H210P support mixed-voltage operation between its two gates?

No, MC10H210P does not support mixed-voltage operation. Both gates share the same VEE (pin 8) reference and require identical −5.2 V ±5% supply. While VCC1 (pins 1, 15) and VCC2 (pin 16) are physically separate, they must both be connected to the same 0 V reference point in standard MECL 10K configurations. The datasheet confirms no specification supports differential or split VCC operation for MC10H210P.

Can MC10H210P be used with modern 3.3 V or 5 V logic families?

No, MC10H210P is strictly an MECL 10K device and incompatible with TTL, CMOS, or LVDS logic families without level translation. Its inputs require negative voltages (VIH = −1.17 V min, VIL = −1.95 V max), and outputs swing between −1.95 V and −0.735 V. Direct interfacing with 3.3 V or 5 V systems would damage MC10H210P or cause logic failure. Level shifters such as MC100ELT20 must be used alongside MC10H210P for mixed-logic designs.

What is the maximum output current rating for MC10H210P?

MC10H210P has a continuous output current rating of ±50 mA per output terminal, with a surge rating of ±100 mA. This rating applies under the absolute maximum conditions defined in Table 1 of the datasheet and assumes proper 50 Ω termination to −2.0 V. Exceeding ±50 mA continuously risks exceeding the 160 mW typical power dissipation limit and may cause thermal instability or parametric shift in MC10H210P performance.

Is MC10H210P available in Pb-free packaging?

Yes, MC10H210P is available in Pb-free packaging as MC10H210PG, indicated by the "G" suffix in the ordering code. The Pb-free version uses the same PDIP-16 (Case 648) mechanical form factor and electrical specifications as the standard MC10H210P, with no performance or reliability trade-offs. Both versions comply with JEDEC standards and share identical thermal and timing characteristics-MC10H210PG is a drop-in replacement for MC10H210P in RoHS-compliant designs.
