Overview

MC10H104FNR2G from ON Semiconductor is a quad 2-input MECL 10H™ AND gate with one gate providing both AND and NAND outputs, 1.0 ns typical propagation delay, −5.2 V VEE supply, and −1.95 V to −0.735 V output voltage swing across 0°C to +75°C. It operates in high-speed digital systems requiring ECL-level logic compatibility and low-skew timing.

For engineers reviewing the MC10H104FNR2G datasheet, pinout, applications, or equivalent options, this part serves as a drop-in performance upgrade over MECL 10K AND gates in telecom line cards, test equipment clock distribution, and high-frequency data path gating where sub-2 ns timing and noise-immune differential signaling are critical.

Technical Context

The MC10H104FNR2G implements four independent 2-input AND functions using MECL 10H bipolar transistor technology, with one gate (Gate A) offering complementary AND/NAND outputs on pins 2 and 3. All inputs accept standard MECL 10K-compatible voltage levels (VIH = −1.17 V min, VIL = −1.95 V max at 25°C), and outputs drive 50 Ω loads terminated to −2.0 V.

It operates from a single negative supply (VEE = −5.2 V ±5%) with VCC1 and VCC2 internally tied to ground via external 0 V connections (pins 1 and 16), enabling simplified power routing in backplane and module designs. Propagation delay remains stable across temperature (0.45–1.9 ns) due to voltage-compensated internal biasing.

FAQ

What is the operating temperature range for MC10H104FNR2G?

The MC10H104FNR2G is specified for operation from 0°C to +75°C. This commercial-grade temperature range is validated across all key parameters including propagation delay (0.45–1.9 ns), output voltage swing, and input thresholds. The device is not characterized for operation below 0°C or above +75°C, and use outside this range may result in undefined timing or logic behavior. Always verify thermal management in the target application to maintain junction temperature within limits.

Does MC10H104FNR2G require a positive supply voltage?

No, MC10H104FNR2G operates exclusively from a single negative supply (VEE = −5.2 V ±5%). Pins 1 (VCC1) and 16 (VCC2) are ground reference terminals and must be connected to 0 V - they are not positive supply inputs. Applying voltage to VCC1 or VCC2 will damage the device. The internal bias network relies on proper VEE and grounded VCC connections to establish correct emitter-coupled logic operating points.

Which pins provide complementary outputs on MC10H104FNR2G?

Only Gate A (pins 4 and 5 inputs) provides complementary outputs: pin 2 is the AND output (Aout) and pin 3 is the NAND output (Bout). Gates B, C, and D each provide only a single AND output (pins 9–10, 15, and 16 respectively) with no associated NAND output. This architecture allows flexible logic implementation where one gate needs both polarities while others perform simple conjunction.

Is MC10H104FNR2G pin-compatible with MECL 10K AND gates?

Yes, MC10H104FNR2G is a functional and pinout duplication of the MECL 10K quad AND gate, as confirmed in the official datasheet. It uses identical pin assignments for inputs, outputs, VEE, and VCC terminals in the PLLC-20 package. This allows direct substitution in existing MECL 10K designs without PCB modification, delivering improved speed and noise margin while maintaining full electrical and mechanical compatibility.

What is the recommended termination for MC10H104FNR2G outputs?

MC10H104FNR2G outputs must be terminated with a 50 Ω resistor to −2.0 V, as specified in the datasheet's test conditions and AC parameter definitions. This termination establishes the correct DC operating point and ensures controlled rise/fall times (0.5–1.8 ns). Using alternative terminations - such as 50 Ω to ground or unterminated lines - will shift output voltages outside guaranteed VOH/VOL ranges and degrade timing performance and noise immunity.
